A vote for Johnson is only a half vote against Trump, while a vote for Hillary is a full vote against Trump.
Bullsh**t. A vote for Johnson is a vote for Johnson. I probably won't vote for Johnson, but I certainly won't vote for Clinton or for Trump, and you may not count my opposition to Trump or to Clinton as half of anything. It is full-on, raging opposition, just as those who will vote for Johnson fully oppose Trump and fully oppose Clinton.
Anyway, I don't care whether any of the Bushes endorses Johnson, but I'm glad to know that they're not supporting Trump. Fully and completely.
Easy big fella. I think he was just laying out the facts objectively. You are completely free to vote for anyone you wish.
