What's there to say about Tim Kaine? Nothing.
Hillary had a Latino VP option and a faux radical option like Elizabeth Warren or Bernie Sanders. Instead, with unfailing Clinton instincts, she chose to triangulate. The trouble though with picking Tim Kaine to cut into Trump's white male lead is that Kaine as a VP has no particular ability to do that. Pandering to the left might have given Hillary a turnout boost. Ditto for Latinos.
Picking Tim Kaine was safe and stupid. And those two words characterize Hillary's safely disastrous campaign which appeals to no one.
