Both Rep. Joe Wilson (R-S.C.) and his Democratic opponent, Rob Miller, have raised almost $2 million combined since the congressman shouted "You lie!" during the president's address on Wednesday night.

Although Wilson has since apologized to the president for his outburst, he has worked diligently to capitalize on his heightened popularity. His recent media blitz -- which included a television interview on Fox News Sunday and a newly minted Twitter feed -- has netted him at least $750,000, though sources did say this weekend he has actually surpassed $1 million.

"[Democrats] want to silence anyone who speaks out against it," Wilson said of the healthcare debate. "They made it clear they want to defeat me and pass the plan. I need your help now… contribute to my effort to defeat the proponents of government-run health care."

So too has Miller embarked on a major fundraising drive. The Democratic challenger seemed financially hamstrung until Wednesday, when he raked in more than $100,000 in donations immediately after Obama's address. That number, however, blossomed to around $1.2 million by this weekend -- an amount only made sweeter by Miller's improved performance in recent polls.

"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 said in a statement released Wednesday. He also labeled Wilson an example of "everything that is wrong in Washington."
