WASHINGTON (CNN) – The Democrat hoping to unseat South Carolina congressman Joe Wilson in next year's midterm elections quickly seized on the Republican's shout of "You lie!" during President Obama's health care speech on Wednesday.
"Representative Wilson's behavior tonight exemplifies everything that is wrong in Washington," Democrat Rob Miller said in a statement provided to CNN. "Instead of engaging in childish name-calling and disrespecting our Commander-in-Chief, Joe Wilson should be working towards a bipartisan solution that makes quality, affordable health care available to each and every South Carolinian.
Miller added: "He owes both the President and the people of this district an apology for his embarrassing behavior during tonight's speech."
Wilson apologized to the president after the speech, calling his comments "inappropriate and regrettable."
Miller, a 13-year veteran of the Marine Corps, gave Wilson the toughest re-election challenge of his career last year in one of the country's most conservative congressional districts. Miller lost by eight points, and decided to challenge Wilson again next year.
National Democrats are also looking for a win: Wilson is on the Democratic Congressional Campaign Committee's 2010 hit list.
Wednesday's commotion is likely to give both candidates a financial boost. Miller's supporters quickly took to Twitter and urged Democrats to support the campaign, while Republicans on the Web urged their readers to donate to Wilson.
Erick Erickson, the conservative voice behind RedState.com, called Wilson a "great American hero." South Carolina Democratic party chairwoman Carol Fowler, meanwhile, said Wilson gave the state yet another black eye.
"Once again a South Carolina Republican has embarrassed our state," Fowler said in a statement, making a nod to scandal-plagued governor Mark Sanford. "Never has any member of Congress shown such disrespect for the president during a speech."
UPDATE: Miller's campaign says they have raised $40,000 since Obama's speech ended tonight.
