I have never, and I will never, trust Mike Pence.
The VP job is attack dog, which Pence has not once assumed. In fact, he has never even been a defense dog – Pence has been completely absent whenever a vigorous defense of Donald Trump has been called for.
True, compare him to Biden, Gore, Cheney, etc. All were far more aggressive in going to the mat for their president. And all were far more aggressive in lining up the Senate leadership.
