Bernie Sanders will be tested in 2020 as he never was in 2016

Democratic hopeful Pete Buttigieg signaled the start of a new political era for Sen. Bernie Sanders, one of the front-runners for the party’s 2020 presidential nomination, with five crisp words.

With those five words during last week’s CNN town hall marathon — “No, I don’t think so” — the South Bend, Indiana, mayor briskly rejected Sanders’ proposal to allow convicted felons to vote not only after, but during, their incarceration. In the process Buttigieg did something that Hillary Clinton almost never did during her 2016 primary contest against Sanders: He directly criticized the substance of one of the senator’s policy proposals. CONT.
