I agree with the others that the test isn't a net positive for Warren. And while I personally like her, I also question how electable she is. I don't think she's as unelectable as Bernie is, but I don't think she'll play well outside of the coasts. I still think she probably beats Trump, but it's iffy. You can probably write off VA and NC, not sure about FL or the upper midwest. There was a piece a few months ago where the journalist asked several Pub stategists which Dems scared them and which they wanted to run against. The ones they wanted to run against the most were Sanders, Warren and Gillibrand. Biden and Booker were the 2 they least wanted to run against, though my fear with Booker is he could have a hard time sealing the deal with progressives, and he admitted to a 1990s grope. Of the people running, I'm thinking Biden or Hickenlooper with Harris as veep would be the strongest ticket.
