From Bernie on twitter - he and Trump may debate:

75. Hillary supporters should actually consider the good that would come of this

I know one angle of this story that partisans will enhance - Bernie will show he's formidable against Trump. Clinton supporters will declare him delusional and presumptuous.

But there's another angle here worth exploring for both Bernie and Hillary supporters.

The party is fractured right now. There are many on the Left and left-leaning Independents who love Bernie but are chilly at best towards Clinton.

But what if Sanders goes toe to toe with Trump? Then the focus shifts. If his supporters, especially Millennials, see Bernie painting Trump as the ultimate enemy in a debate, they may find shifting to Clinton much more comfortable.

He could bring reticent or disillusioned supporters into the NeverTrump camp by nakedly exposing Trump's danger.

So, it feels kind of win-win to me. Bernie has the potential to gain further influence in the party, but he'll also be uniting the party by singling out the common enemy.

Part of me wants to say, "Going after the Republican nominee should be the Democratic nominee's prerogative." I want to go, ooh, poor form. But . . .

But if the goal is unity and shifting focus, this could work well for Clinton in the general.
