Sen. Elizabeth Warren is progressives' runaway favorite for president in 2016, with Sen. Bernie Sanders in second place, a new poll shows.Sanders, I-Vt., who says he's considering a presidential run, edged out former Secretary of State Hillary Rodham Clinton, 24 percent to 23 percent, according to Democracy for America's first 2016 Presidential Pulse poll of its members.More than 42 percent of respondents wanted Warren to run for president, although she has said she's not running. Warren's strong showing wasn't a surprise, but Sanders' placement ahead of Clinton shows "the race for the Democratic nomination is far from locked" among progressives, according to the group, founded by former Vermont Gov. Howard Dean."If they decide to get in the race, our poll clearly shows that any number of candidates could win Democracy for America members' support, especially if they focus their campaign on combatting income inequality, the driving issue of the 2016 campaign," Charles Chamberlain, DFA's executive director said in a statement.
