Sanders, Clinton, Biden? Democrats mull possible 2020 challengers

Democrats are unenthusiastic about their choices of possible candidates to challenge President-elect Donald Trump in four years, a new poll shows.

A USA Today/Suffolk University poll out Wednesday showed that Democratic and independent voters are most excited about "someone entirely new" running for office in the next presidential cycle.

Hillary Clinton, who lost to Trump in November, should not run again, according to 62 percent of respondents to the poll. Twenty-two percent of those polled said that Clinton running would excite them, but about 15 percent said that another run at the presidency by Clinton would "make no difference."

Current Vice President Joe Biden's and Vermont Sen. Bernie Sanders' numbers were better — they did about twice as well as Clinton, according to CNN.

Biden has said he has no plans to run in 2020.

According to CNN, "about a third of respondents said they would be excited by a 2020 bid from Massachusetts Sen. Elizabeth Warren, and former Massachusetts Gov. Deval Patrick was overwhelmingly unknown."
