Barack Obama raised $32 million in January alone and attracted 170,000 new donors, campaign manager David Plouffe said in a conference call with reporters Thursday morning.

The haul was the most money the campaign has raised in a single month and matched the Illinois senator's best three-month period last year, aides said.

The windfall positions the presidential candidate to shell out for the Feb. 5 Super Tuesday primaries, when 22 states will hold Democratic contests.

Obama is already advertising in all but two of the Feb. 5 states, and Plouffe said the Obama campaign plans to go on TV and radio airwaves soon in states voting after Feb. 5, including Louisiana, Nebraska, Washington, Indiana and Virginia.

"We think that the strength of our financial position and the number of donors does speak to financial sustainability if it ends up going through March and April," Plouffe said. "We think we will have the financial resources to conduct vigorous campaigns in the states to come."

Spokesman Bill Burton said the $32 million haul represents the most money raised in one month in Democratic presidential primary history. He said John Kerry brought in $44 million in April 2004, but he was already the established nominee and the money was for the general election.

Obama's biggest single day of fundraising came after he finished second to Hillary Clinton in the January 8 New Hampshire primary, his campaign reported.

Obama, who won the leadoff Iowa caucuses Jan. 3, rebounded from his losses in New Hampshire and Nevada on Saturday with a big victory in the South Carolina primary.

Clinton is still leading the polls in several delegate-rich Feb. 5 states like California and New York, and has also been an aggressive fundraiser.

They both raised more than $100 million in 2007 -- but while the Clinton campaign has not released its January totals, Obama's fundraising for the month was expected to eclipse hers.

The Clinton campaign did not show concern.

"Once people start voting that's a more important measure of performance," said Clinton spokesman Jay Carson. As for money, "That's one measure of a campaign."

Clinton spokesman Phil Singer said, "We will have all the resources we will need to compete and win."

Plouffee said the Obama campaign is "more confident" it will meet delegate goals on Tuesday and is trying to convince supporters of John Edwards, who dropped out Wednesday, to cross over.

The number of new donors in January exceeds the number Obama attracted in any previous fundraising quarter, and brings the campaign's total to 650,000 donors.

Plouffee said less than 3 percent of the campaign's donors have hit their contribution limit of $2,300, meaning the fundraising reservoir can still be tapped for more money.
