Patrick Ruffini, a GOPer but perceptive web techie, projects that Obama's Campaign is going to hit $60M in fundraising for the month of February alone:

 According to my initial projections off this crowdsourced spreadsheet of Obama donations I set up after the Wisconsin victory, Obama has already raised at least $45 million for February and is on track to raise $60 million for the month.

A source who tracks Obama's public donation number like a hawk tells me that Obama had tallied about 256,000 donors for the year as of the end of January. Those donors produced $36 million in receipts, for an average contribution of $140.

Obama's public donor count stands at 583,525, meaning about 327,000 people donated in February. With the same average, that would give Obama just over $46 million in 21 days.

This is in line with the expectations game they are playing. The campaign says they will raise at least $36 million in February. You can bet that they wouldn't say that if they hadn't already passed the mark, plus a decent sized buffer. Their lowered expectations call for them to beat January's total, when they will in fact blow them out.

He goes on to say that he believes Obama's campaign will quite possibly hit $70M.

What this reflects is not simply Obama-mania but a highly mobilized Democratic base rallying around the perceived leader.
