Yet another Connecticut Republican has launched a television advertisement for a primary that's 10 months away -- a move that underscores how competitive and expensive the contest to oust Sen. Christopher J. Dodd has become.

Former Ambassador to Ireland Tom Foley hit the airwaves Tuesday with his second ad.

He follows fellow Republican and former World Wrestling Entertainment CEO Linda McMahon, who went up on the airwaves in September and again last week for just one day, while President Obama was in Connecticut to raise money for Dodd.

Linda McMahon's background as a pro wrestling impresario has prompted any number of jokes since last week when she launched her bid for the Republican Senate nomination in Connecticut. But it took mere days -- and a big-money campaign ad run -- to show that the first-time Republican candidate is dead serious about trying to unseat Democratic incumbent Christopher J. Dodd.

McMahon dipped into the wealth she has amassed as CEO of publicly-traded World Wrestling Entertainment to finance a seven-figure television ad buy. Her campaign has two ads running on network television in the New York City media market -- the nation's biggest and most expensive -- and across Connecticut for the next seven days.

McMahon's campaign also launched an introductory radio spot yesterday to air statewide for one week; took out full-page ads in local newspapers; sent out mailers; and has Web ads up targeting Connecticut voters.

Linda McMahon, the chief executive officer of World Wrestling Entertainment, announced Wednesday that she has joined the contest for the 2010 Republican Senate nomination in Connecticut.

Her entry adds a good deal of personal wealth -- and perhaps a bit of her sports marketing firm's trademark theatrical flair -- to the already crowded field of Republicans seeking to challenge Democratic Sen. Christopher J. Dodd. Suffering from a job approval slump tied to questions about his oversight of the financial industry as chairman of the Banking Committee, Dodd is more vulnerable than at any previous point in his Senate career.

McMahon, who stepped down from her CEO post to run, released a statement Wednesday touting her business experience as a key qualification for the seat. "I have spent the past 30 years growing what began as a 13-employee small business into a publicly traded, global entertainment company," she said. "I understand what it takes to balance a budget, create jobs and grow the economy."

She has run the company with her husband, Vince McMahon, a showman who long has been the public face of pro wrestling and its flamboyant mixture of sports and theater.

Former Connecticut Rep. Rob Simmons isn't wasting any time in trying to consolidate local party support for his Senate bid in what could be a crowded primary.

The Simmons campaign announced on Monday it had secured the endorsement of Deputy House Republican Leader Bill Hamzy, a former Connecticut Republican Party chairman, adding to a string of GOP endorsements this summer that now includes state House Republican Leader Larry Cafero, state Sen. Tony Guglielmo and 20 members of the Republican State Central Committee.

The party will endorse a candidate to take on Democratic Sen. Christopher J. Dodd, who is battling the lowest approval ratings of his career, at its convention, which is slated for May 21-22, 2010. Other candidates can still run in the primary, but the party nod could provide important momentum.

Backers of Republican Rep. Ron Paul's 2008 presidential bid are working their fundraising magic with prospective Connecticut Senate candidate Peter Schiff.

They've rallied around Schiff, a libertarian financier and former Paul presidential adviser, helping him raise $528,000 since announcing in mid-July that he was formally exploring a challenge to incumbent Democrat Christopher J. Dodd. And today they are launching a "money bomb" -- the type of one-day online fundraising push that helped Paul net more than $6 million in a 24-hour-period in December 2007 -- that Schiff organizers hope will bring in $200,000 more.

Schiff is considering entering the crowded Republican field to take on Dodd, one of the most vulnerable Democratic incumbents in 2010. He is using his fundraising efforts to test his viability as a candidate, telling backers last month that his decision "is largely dependent on the level of early support and contributions I receive from people like you."

Both major parties' congressional campaign units make a practice of setting up joint fundraising committees. These operations share the contributions they receive between the national party organization and individual candidates who are up for election in the current cycle.

But a Democratic fundraiser held in June, from which the Democratic Senatorial Campaign Committee (DSCC) netted the lion's share of the proceeds, highlights the fact that having a joint committee usually does not mean a 50-50 split.

The event on June 15 event at the Ritz-Carlton Hotel in Chicago, was headlined by White House Chief of Staff Rahm Emanuel, a former House Democrat from Illinois. And it raised more than $600,000 for "Senate Victory 2010."

Connecticut Republican Peter Schiff is using donation levels over the next few weeks to gauge support for a potential Senate run in 2010. But he might want to make a note of the experience of political mentor, Texas Rep. Ron Paul, whose 2008 presidential campaign experience demonstrated that a huge number of donations do not necessarily denote electoral viability.

Schiff alerted supporters Tuesday that his campaign Web site is now accepting donations.

"My decision to run is largely dependent on the level of early support and contributions I receive from people like you," he wrote in the e-mail. Recent polling, he said, has convinced him the race is "winnable," and "now it's up to the people to show their support because no candidate can win this race alone."

Despite a heavy policy load that includes shepherding the Democrats' health care overhaul through the Senate, Connecticut Sen. Christopher J. Dodd somehow found time to conduct a good deal of fundraising over the past three months. The five-term incumbent announced Monday that he raised $1.2 million in the second quarter, besting his first quarter total of $1 million and leading all comers is what is expected to be a heavily contested 2010 race.

Campaign manager Jay Howser, however, underscored in a statement that "unlike so many of his competitors," Dodd's "fundraising took a back seat to his primary job: working for the people of Connecticut in the U.S. Senate" on issues like consumer protection, health care and the overhaul of the financial regulatory system.

Dodd's campaign boasted that the senator "received more individual donations from Connecticut than any other state," after coming under criticism when its first-quarter fundraising report revealed just five Connecticut residents donated. The campaign also counted 1,700 small-dollar donors who contributed $200 or less, but did not release details on how much money it raised from large donors or political action committees. Dodd raised more than 40 percent of his contributions from PACs in the first quarter, with finance industry, health care and labor committees leading the way.

Investor and financial commentator Peter Schiff confirmed Tuesday night that he is "potentially considering" a run for U.S. Senate in Connecticut.

Schiff, a frequent guest on CNBC and Fox News who predicted the current financial crisis several years ago, made a visit to Comedy Central's The Daily Show with Jon Stewart to hawk his book, "Crash Proof: How to Profit From the Coming Economic Collapse" But the interview quickly veered into politics, with Schiff launching into a critique of both the Bush and Obama administration's economic policies.

"Are you running for office?" Stewart finally asked.

Two Senate Democrats have joined a challenger for an open seat in forming a joint fundraising committee for 2010 with the help of the Democratic Senatorial Campaign Committee.

All three are in competitive races in Senate Victory 2010 fund created May 28. The fund will benefit Sens. Christopher J. Dodd of Connecticut and Michael Bennet of Colorado, and Missouri's Secretary of State, Robin Carnahan, who seeks the seat of retiring Republican Sen. Christopher S. Bond.

Such joint fundraising committees allow candidates to hold single events with contributors writing a single check for multiple candidates, who then split the proceeds with the national committee. But they also create accounting headaches because contribution limits from individuals still apply. For example, if a contributor has already given the maximum $2,400 per election to Dodd, any contribution to the joint committee must be divided among the others.

The race to take on Democratic Sen. Christopher J. Dodd in Connecticut is going to be a crowded affair, with three Republicans now in the mix. The latest to jump in is businessman and former Ambassador Tom Foley, who announced Wednesday in Stamford, Conn., that he would run for the GOP nomination.

Foley is looking to paint himself as "a Washington outsider and expert in business and economics," as he says on his new Web site. He was, however, a fundraiser for President George W. Bush, and was appointed U.S. Ambassador to Ireland in 2006. He promised supporters Wednesday afternoon that he would "bring fresh ideas, new energy, and real expertise to the problems we face in Connecticut and across the country.

His low profile and lack of political experience make him a virtual unknown in Connecticut, a disadvantage against his GOP opponents -- former Rep. Rob Simmons and state Sen. Sam Caliguiri. However, Foley's successful business forays, including stints at consulting firm McKinsey & Co. and Citicorp Venture Capital and now owner of several companies, make it likely he will be capable of self-funding.
