He's a very credible candidate. I'm not going to be presumptuous. No one's going to say it's going to be a pushover.

It would be presumptuous for anyone at this stage to suggest that is, or is not, what's going to happen. But it certainly is one of the options that is available,

inherently improbable and not credible.

That's very presumptuous on their part.

I think that would be very presumptuous of me to do, since I have not had one vote yet in the Democratic primaries, ... I can tell you flat-out that I did not ask him to be my running mate.

There's not a shred of credible evidence he was ever in that car.
