Clinton is banking on the Obama coalition to win

Hillary Rodham Clinton is running as the most liberal Democratic presidential front-runner in decades, with positions on issues from gay marriage to immigration that would, in past elections, have put her at her party's precarious left edge.

The moves are part of a strategic conclusion by Clinton's emerging campaign: that it can harness the same kind of young and diverse coalition as Barack Obama did in 2008 and 2012, bolstered by even stronger appeal among women.
