UPDATE 5:21 p.m.: Wilson is now well over $700,000, according to a GOP source, while Miller is at $800,000. Expect Wilson to pass Miller soon enough, the source said. -Aaron Blake

Both Rep. Joe Wilson (R-S.C.) and his Democratic challenger have raised some serious cash since the congressman shouted "You lie!" during the president's address on Wednesday night.

Wilson's outburst has netted his campaign about $200,000 in the past two days, CNN reported on Friday. The lawmaker has also embarked on a media blitz of sorts, taking to YouTube and Twitter to raise additional money while making his case against the president's health care plan.

"On these issues, I will not be muzzled, I will speak up and speak loudly against this risky plan," Wilson said in a video posted to his Web site.

"[Democrats] want to silence anyone who speaks out against it," Wilson added. "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."

But Wilson's spoils hardly compare to what his Democratic opponent, Rob Miller, has raised in recent days: more than $750,000. Miller has even turned Wilson's gaffe into his own online fundraising drive. On Thursday, the candidate's Web site automatically re-directed visitor's to ActBlue's fundraising page. Late that evening, Miller e-mailed supporters in an attempt to top $1 million by the week's end.

"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."
