Senator Barack Obama is leading in delegates - and dollars.
He raised a record $55 million February. That far outpaces the previous record of $36 million -- which Obama set in January.
But Senator Hillary Clinton isn't about to be undone.
She raised at least $4 million online -- just since her big wins in Ohio and Texas on Tuesday.
And Clinton is on the offensive on the campaign trail.
"Senator McCain will bring a lifetime of experience to the campaign, I will bring a lifetime of experience, and Senator Obama will bring a speech he gave in 2002," Clinton said.
Obama's camp has not responded to the attack but one of his top advisor's referred to Clinton as a "monster" -- a remark the Obama campaign repudiated.
Meanwhile, the New York Times reports that the Republican National Committee has more money than the Democrats.
The Republicans have $25 million on hand while the Democratic National Committee only has about $3.7 million.
