Obama raises record $55 million

By Caren Bohan

CHICAGO (Reuters) - Barack Obama raised a record $55 million in February, beating rival Hillary Clinton's total and ensuring a big-spending battle for the Democratic presidential nomination in the months ahead.

Obama's haul, announced by aides on Thursday, was a fund-raising record for a single month. It trumped Clinton's $35 million in February and gave the Illinois senator some much needed good news after two critical losses in Ohio and Texas.

Clinton dodged a possible knockout blow in the presidential race with the wins over Obama on Tuesday, setting up a long and bruising fight for the Democratic nomination to face Republican John McCain in November's election.

The New York senator raised $4 million over the Internet since her big wins and $6 million since the month began, her campaign said.

Clinton spokesman Howard Wolfson criticized Obama's promise to be more aggressive in the aftermath of Tuesday's losses and likened him to independent prosecutor Ken Starr, a lightning rod for Democratic criticism during the 1998 probe that led to President Bill Clinton's impeachment.

"I for one do not believe that imitating Ken Starr is the way to win a Democratic primary election for president, but perhaps that theory will be tested," Wolfson told reporters.

Starr led an investigation of Bill Clinton, Hillary Clinton's husband, which focused on Clinton's denials under oath about his sexual relations with White House intern Monica Lewinsky.

The House of Representatives impeached Bill Clinton on perjury and obstruction of justice charges, but he was acquitted in a Senate trial. Starr's probe was attacked by Democrats as politically motivated.
