Still, Ball has met the threshold set by the National Republican Campaign Committee to enter the first tier of its Young Guns program, which provides aid to promising recruits. "By achieving 'On the Radar' status, Ball has already proven his ability to build a successful campaign structure and achieve important fundraising goals," the NRCC said in a release when Ball reached that stage, in August.

That year, he defeated six-term incumbent Sue W. Kelly by 2 percentage points. President Obama narrowly won the 19th District in the 2008 election, 51 percent to 48 percent for Republican John McCain.

Hall has not filed his third quarter report either. The filing deadline is Thursday at midnight.
