Obama raises $7M

The remarkable outpouring of contributions recorded since Tuesday's contests in 22 states comes on the heels of an eye-poppping $32 million raised by Obama in January and the record-shattering $100 million each Obama and Clinton raised in 2007 in their neck-and-neck race for the Democratic presidential nomination.

Obama has been riding a wave of fundraising from large donors and small Internet contributors. While not matching Obama's pace, Clinton also saw an online surge of donations from 35,000 new contributors since midnight Tuesday, Clinton campaign aides said.
