Elizabeth Warren is staying painstakingly neutral in the Democratic presidential contest -- for now.
Candidates Hillary Clinton and Bernie Sanders would both love to win the endorsement of the populist senator from Massachusetts -- especially with the important primary in next-door New Hampshire on Tuesday.
Warren is idolized by an army of liberal voters. And her longtime antipathy toward a financial system that she says is rigged against average Americans taps into one of this year's dominant Democratic themes.
Many Democrats say Warren faces a complicated decision best addressed by letting the 2016 contest percolate longer. For now, she's using her leverage to make her progressive agenda a guiding principle for the candidates.
Warren is the only one of the Senate's 14 Democratic women who hasn't endorsed Clinton.
