A few weeks ago, I wrote that I wasn't concerned about Sanders remaining in the race until the very end, because he doesn't wish to see a President Trump and will ultimately throw his full support to Clinton. Sanders has, indeed, lightened up on Clinton and is instead trying to shape the Democrats' platform and direction. But his attacks on the party have released something just as damaging to the causes he professes to represent. Coupled with his refusal to raise money for the party, his increasingly harsh rhetoric could hurt Democrats up and down the ballot in November and beyond.
