When will the candidates start vetting potential running mates?

Out of the people who have actually endorsed Sanders, Grijalva, Welch, and Peterson are nobodies, Ellison will lose votes because of his religion, Gabbard is far too similar to Palin, and Grayson is dangerously insane. Kaptur could help out in Ohio, but that's the only place that I know of. She should instead go with a progressive who's stayed neutral, or endorsed her.

Like Hilda Solis?  

Solis doesn't have the name recognition. Elizabeth Warren could work.

I don't see what's so bad about picking Welch. Joe Biden wasn't exactly a household name in 2008, either.

Welch has more use in the House, where he's part of the Democratic Party leadership. And Joe Biden wasn't a house name, but he had given decades of service representing the people of Delaware. Welch has been around for a while, but not long enough to justify a nod as running mate.
