"There should be no misunderstanding. The decision by a conservative Supreme Court to uphold the president's healthcare law generated tremendous enthusiasm and financial support for our committee and our candidates," Canter said in a statement. "I'm sure Republicans are also raising plenty of money from their supporters by proclaiming their plans to fully repeal the law, but many of them know that undecided voters are ready to move on and focus on the economy and creating good paying jobs."

The news follows record high fundraising reported by the Democratic Congressional Campaign Committee (DCCC). That group pulled in $2.3 million between Thursday, the day the court handed down its ruling, and Saturday.

The healthcare decision was a fundraising boost for Republicans as well, with Mitt Romney's campaign reporting it raised $5.5 million from 55,000 individual donations within 24 hours after the ruling. 

The Obama campaign claimed they outraised Romney's numbers, but did not provide numbers.
