After Trump secures the nomination, they'll run an independent; Romney or Bloomberg, in a handful of key battleground states to throw the election to Hillary. They can play ball with her.

That's what we're up against.
And there is nothing to stop us from exacting electoral revenge on them via the same, and other methods.
