Dilbert suggested Perez, but there is the obvious issue of a Latino VP who can't speak any Spanish.
Clinton - Vile-Sack and Clinton - Book-Her have bumper sticker problems.
"Clinton with her Kaine" and "Clinton - Kaine - crooked" may have seemed to be the least bad of a number of bad options to her advisers, late at night and after way too many pizzas and beers.
Anyway, I'm quite pleased with her choice! Nothing like a gun-grabbing Democrat from Virginia to bring out the single-issue white rural voters in November!
