Despite his recent losses in Nevada and South Carolina, presidential candidate Bernie Sanders remains a fundraising powerhouse, raising $38 million and counting in February for his bid for the Democratic Party's nomination.

Sanders is racing to collect $40 million before the end of the day. That's nearly two times the $21 million the Vermont senator raised in January. This morning, his tally was at $36 million; by noon he had raised $1 million more. By 3 p.m., he had hit $38.19 million.

Sanders also released a national television ad Monday in which he outlines how he believes "corrupt politics" and political contributions from the wealthy contribute to a "rigged economy."
