Bernie is also, unlike Hillary, an insurgent candidate who has never in his career been part of any "political establishment." In this year when voters (albeit especially on the right) are distrustful of "establishment" politicians, matching Trump in this respect could further strengthen Bernie's ability to take down the Donald.
If Bernie were to prove adept at getting under the Donald's skin, if he provokes exchanges (through the media) in which he regularly gets the better of Trump, it's just possible that Democratic voters will recalculate their "electability" assessments in his favor. Not likely, but perhaps not impossible.
If the far more likely scenario plays out, however, and the Party makes Hillary its standard-bearer for the fall, Bernie will nonetheless have brought still more credit to his campaign by helping to protect America from a President Trump, and to erode the power of the Republican Party that has for years been preparing the path for Trump's kind of demagogic fascism to rise and threaten the nation.
