Washington (CNN) - The Democratic Congressional Campaign Committee announced a $250,000 TV ad buy Wednesday for the special election in New York's 26th district, according to a Democratic source, one day after the conservative group American Crossroads announced a $350,000 ad buy in the same district.
The May 24th special election that pits Republican New York State Assembly member Jane Corwin against Democrat Kathleen Hochul and independent Tea Party candidate Jack Davis, a conservative former Democrat, is becoming a referendum of sorts on the House GOP budget plan.
The National Republican Congressional Committee brought their Congressional big guns into the district for fundraisers, including House Speaker John Boehner and House Majority Leader Eric Cantor and released web ads criticizing the records of Hochul and Davis.
A Wednesday NRCC web spot links Davis to President Obama and Democratic Leader Nancy Pelosi.
"Jack Davis' Democrats have their hands all over Washington; lets not hand them Western New York," the ad says.
Meanwhile, Hochul has criticized the Medicare privatization plan in Rep. Paul Ryan's budget passed by the House Republican majority. One Democratic source said the Medicare vote is hurting Republicans in the Western district, where Republican voters greatly outnumber Democratic voters.
"The 2012 House budget, that my Republican opponent supports, further fuels the profits oil companies," Hochul said in a statement. "House Republicans would rather gut alternative energy technologies and decimate Medicare, than cut subsidies for big oil. How is that competitive?"
Also Wednesday the conservative FreedomWorks Political Action Committee announced a campaign to expose "Jack Davis' real record as a big government liberal," even though he is running as an independent candidate.
"Out of respect for this decision, the candidates have a responsibility to be honest about their positions on the issues. Considering Jack Davis' leftist resume, his candidacy as a 'tea party' candidate is either a sad attempt to raise his own personal political profile or an underhanded strategy to hand the seat to the Democrat contender," FreedomWorks President Matt Kibbe said in a statement. "Either way, it's a slap in the face to New York 26 voters and the larger tea party movement and FreedomWorks PAC will ensure that this message is delivered throughout the district in advance of the May 24th special election."
The seat was vacated amidst a high-profile scandal when Republican Rep. Chris Lee resigned in April after the website Gawker exposed correspondence the two-term married Congressman had with a woman via Craigslist. He allegedly sent a bare-chested photo of himself to the woman.
