Hillary Clinton has held discussions on the 2020 presidential election with at least four potential Democratic candidates, Axios reports. The report, citing an unnamed source close to Clinton, names Sen. Elizabeth Warren, Sen. Cory Booker, Colorado Gov. John Hickenlooper, and Los Angeles Mayor Eric Garcetti as those who have sought advice from the 2016 candidate. “A bunch have picked her brain,” said the source, adding that Clinton will talk to any Democrat who wants her advice. The source said: “The savvy ones know she’s the most valuable endorser in the party not named Obama.” Her openness is reportedly fueled by her desire to get rid of Donald Trump, with the source saying: “Hillary wants Trump gone... She doesn’t know who’s best able to beat him, but she knows about grueling nomination fights.” Nick Merrill, Clinton’s spokesman, said: “I won’t comment on private discussions she’s had except to say that she’s more than happy to talk to anyone considering a run about the challenges (as well as the great things) that go with it, and lessons learned on what to watch for in this next cycle (aside from Vladimir).”
