Outspoken freshman Rep. Alan Grayson raised more than $500,000 for his re-election effort during a one day online “money bomb” event held Monday.

Grayson’s Web site, www.congressmanwithguts.com, broke the half-million dollar fundraising mark early Tuesday morning and in a press release the campaign announced that contributions, generally of less than $40 each, came in from more than 13,000 people.

“What we’ve demonstrated is that you can finance a campaign for a competitive district in an expensive media market through People Power. Not by sucking up to lobbyists, special interests or favor-seekers,” Grayson said in the news release.
