WASHINGTON — During the depths of the economic crises that consumed his first term, President Barack Obama helped pluck a Harvard professor named Elizabeth Warren out of relative obscurity and made her the face of his campaign to curtail Wall Street banks.
Now Warren, who parlayed that platform into a Senate seat from Massachusetts, is showing a willingness to take a stand against Obama, magnifying rifts in the Democratic Party and sparking speculation about her own presidential ambitions.
Despite their shared history, Warren and the White House have a political incentive in using each other as a foil.
For Obama, creating distance with Warren may be seen as a tack to the center that clears the way for striking deals with Republicans, which is likely to be the only way he can rack up legislative achievements during his final two years in office. Next month, the GOP will hold a commanding majority in the House and a comfortable edge in the Senate.
For Warren, splitting with the president, particularly on economic issues, helps solidify her as a populist champion and perhaps opens a lane for challenging expected Democratic presidential candidate Hillary Rodham Clinton.
"We are in a moment on economic inequality and that is the defining fight of Elizabeth Warren's life," said Anna Galland, executive director of the progressive group MoveOn.org, which has launched a $1 million effort to draft Warren for the 2016 campaign.
Warren has repeatedly shot down speculation of a White House run. In an interview with NPR that aired Monday, she said, "I am not running for president" — but pointedly avoided answering whether she was also ruling out running for president in the future.
The draft Warren campaign has picked up momentum following her high-profile split with Obama last week over a $1.1 trillion spending bill to keep the government funded through Sept. 30. Warren balked at a provision that weakened regulations on complex financial instruments known as derivatives that were included in the 2010 Dodd-Frank financial reform legislation.
