Four out of every five House members who didn't side with their party on the health care bill represent districts that voted for the opposite party's presidential nominee in the 2008 election.

The party-buckers on the 220-215 vote on Saturday night included 39 Democrats who voted against the bill. Of them, 31 represent districts that voted for John McCain over Barack Obama. Republicans are targeting many of them for defeat in the 2010 election. Of the other eight, three are serving their first terms in districts in which they defeated or succeeded Republicans in the 2008 election.

Eighteen Democrats from McCain-voting districts backed the bill. Among this subset, seven-term Rep. Marion Berry of Arkansas represents the most pro-McCain district (59 percent). He's more politically secure than other "McCain Democrats" who voted for the bill, including first-term Rep. Tom Perriello of Virginia and second-term Rep. Zack Space of Ohio.

Virginia Rep. Tom Perriello has drawn a 2010 challenge from state Sen. Robert Hurt, the latest and highest-profile opponent to the first-term Democrat.

Hurt said Wednesday that he filed candidacy paperwork with the Federal Election Commission to prepare a challenge to Perriello, who upset Republican Rep. Virgil Goode in the 2008 election.

The National Republican Congressional Committee circulated Hurt's announcement press release to reporters, a sign that the campaign arm of House Republicans prefers Hurt as its candidate in a conservative-leaning district it hopes to wrest from Democratic control.

The conservative Family Research Council's political action committee plans to target 16 congressional races in 2010. The group's president, Tony Perkins, said the PAC has a goal of raising $1 million to boost grassroots activity in targeted races.

The group wants to spend money to help favored candidates take over the seats now represented by:

Sen. Michael Bennet, a Democrat who is running for a full term in Colorado after his appointment this year;

Sen. Christopher J. Dodd, a Democrat who is running for re-election in Connecticut;

New Hampshire Sen. Judd Gregg, a Republican who is retiring;

Missouri Sen. Christopher S. Bond, a Republican who is retiring;

Rep. John Boccieri, a Democrat who represents Ohio's 16th District;

The three Virginia Democrats who replaced Republicans after the 2008 election will be raising some campaign funds together as they prepare for their House re-election campaigns.

Virginia Freshmen Victory Fund was established Monday with the Federal Election Commission as a joint fundraising committee that will collect funds and then divvy them up among the campaign committees of Reps. Glenn Nye of the 2nd District, Tom Perriello of the 5th District and Gerald E. Connolly of the 11th District.

The victories of Nye, Perriello and Connolly enabled Democrats to increase their House majority in the 2008 election, but the Republicans are targeting all three Democrats in 2010.

Colorado Rep. Jared Polis has a lot of fundraising clout for a guy with a mere seven months of House service.

The Jared Polis Victory Fund, a joint fundraising committee the wealthy freshman congressman organized in May, donated $139,500 in late June to 31 Democratic campaign committees, according to a filing Friday with the Federal Election Commission.

The largest chunk of funds, $30,000, went to the Democratic Congressional Campaign Committee, the campaign arm of House Democrats that will be defending the party's 256-178 majority in the 2010 elections.

While members of Congress are home for recess, the Pharmaceutical Research and Manufacturers of America (PhRMA) is using a $2.5 million ad campaign to boost the health care records of several potentially vulnerable House Democrats.

Television commercials began running June 27 in six members' home districts and will air for two weeks. Accompanying mailers were also sent to voters.

"On health care there are two sides of the coin. On one side, do nothing. On the other, move forward- like Congressman Jim Himes, who's making real progress on reform," said the voiceover in one targeted television ad. The commercial continues by crediting Himes for expanding coverage for children, veterans, and protecting Medicare.

The campaign arm of Republicans in the U.S. House is using this week's legislative recess to criticize some Democrats who backed a climate change bill the House narrowly passed last week.

The National Republican Congressional Committee's advertising campaign consists mainly of low-cost radio advertisements and telephone calls against 14 Democrats, most of them from conservative-leaning districts, who helped provide the winning 219-212 margin in the June 26 vote. Eight Republicans also backed the climate change bill, which most Republicans described as a massive "national energy tax" on consumers.

A top target of the NRCC campaign is first-term Virginia Rep. Tom Perriello, who broke with most politically vulnerable Democratic freshmen in backing the bill. The NRCC is airing a television ad in Perriello's south-central Virginia district that urges viewers to "tell him he was wrong to vote for the [Speaker Nancy] Pelosi energy tax."
