This is interesting considering blacks are overwhelmingly for Hillary. White Hillary voters must be going for Van Hollen by North Korea margins. Who are the Sanders/Van Hollen voters?
Wow, Edwards really should have endorsed Bernie. Black Hillary supporters probably still support Edwards. White Hillary supporters are already strong Van Hollen. Bernie supporters are suddenly more likely to vote Edwards. Especially the 30% who are undecided.
As for the question, many might sort of be picking randomly since they both endorsed Hillary.
