Self-described democratic socialist Bernie Sanders isn’t socialist enough for many socialists.

“He is for reforming capitalism, not changing capitalism,” Stephen Durham, the 2012 presidential nominee of the Freedom Socialist Party, told Bloomberg. “He is really a lot closer in ideology to Hillary Clinton than he is to me.” Bloomberg speaks to others and finds an endless debate over whether the Vermont senator challenging Clinton for the Democratic Party’s presidential nomination is a bona fide socialist. “I don’t think he is a socialist. He ignores socialist countries,” said Gloria La Riva, the 2016 presidential nominee for the Party of Socialism and Liberation. Sanders will debate Clinton and three other Democratic presidential hopefuls Tuesday night.

Second endorsement for Sanders: Sanders is apparently progressive enough for congressional progressives. On Monday, the co-chairman of the Congressional Progressive Caucus, Rep. Keith Ellison, became the second member of Congress to endorse Sanders. “I’m endorsing Bernie because he is talking about the issues that are important to American families,” Ellison, a Minnesota Democrat, told MSNBC through his spokesman. Sanders’ first endorsement came from Ellison’s co-chairman Raul Grijalva, an Arizona Democrat.

Trump to tweet: Donald Trump is planning to live-tweet the Democrats’ debate Tuesday night, even though he says he expects it will be “a very boring two hours.” Trump, the billionaire running for the Republican presidential nomination, made that announcement Tuesday morning on Twitter.

Biden keeping options open: Vice President Joe Biden, who has been considering a White House bid, doesn’t plan to be on stage when the Democrats debate. At least not Tuesday night. The New York Times writes Biden’s aides are researching filing deadlines to see if he can keep his options open into November. Biden had initially said he would decide on a presidential run by the end of summer.

Bush’s health plan: Former Florida Gov. Jeb Bush is proposing to repeal and replace President Barack Obama’s health-care law with one that would increase tax credits for individuals and allow them to buy coverage protection against “high-cost medical events.” The Associated Press writes Republican presidential candidate Bush is expected to release details of his plan Tuesday, during a three-day trip through New Hampshire. It guarantees coverage for people with pre-existing health conditions, something Obama’s health law also does.
