OK, Bernie Sanders is now getting a lot of tough media coverage. This is a *good* thing, and should be welcomed — even by Sanders supporters 1/
The truth is that Sanders hasn't really been vetted until now. And everyone understands why: his Democratic rivals were afraid to go too negative out of fear that outraged Bernie Bros would stay home in the general election 2/
But Trump won't show that kind of restraint. So now is the time for the Sanders campaign to figure out how to deal with questions about things he said about Castro, the cost of his Medicare plan, and all that 3/
If he can weather the storm, great — better to have it happen now than emerge as a series of Comey-letter-type shocks during the general. If he can't, well, he shouldn't be the nominee 4/
Think of this as stress-testing. You can make a case that Sanders's history isn't really that troubling. In fact, I expect to be making that case if he gets the nom. But he needs to make that case himself — openly and honestly — now, rather than be on the ropes later 5/
