Get why progressives are upset that Warren, Bernie, Brown, Perez, Castro, or Booker aren't the VP nominee, but the campaign feels that Trump has alienated enough women and Latinos that the middle is where they win. Pence was a panic pick to throw to shore up far right social conservatives.
Race boils down to FL, PA, and VA. Even if Trump wins all red states and swing states other than FL and VA, he still loses without PA. CO and NV are huge problems for Trump and shitting on Kasich was insane. Kaine holds VA and helps in FL. CO, NV, and AZ are pure gravy.
Dems don't need to win White college grads, just keeping it close hurts Trump. Kaine helps there big time. Bloomberg's endorsement also helps with college educated Whites too.
As usual, Trump will flip out. Cuban lights up Trump every time. Bloomberg is at a minimum 4 times wealthier than Trump. He's so fucking thin skinned and insecure and Bezos, Bloomberg, and Cuban rattle him every time.
