1) if there really was a video showing Cruz clearly bribing a delegate, it would be plastered everywhere, and Trump wouldn't be able to shut up about it, and;
2) Any politician who was going to bribe a delegate would have to be an utter Moro to do it himself, in the open, with cash. Whatever his flaws, Cruz isn't a moron, and;
3) $100? That's all it takes? That alone makes it seem incredibly implausible that this was a bribe for a vote at the convention.
But hey, post the link and I'll look at it.
