I can't remember one.
When there is more discussion about possibly replacing your candidate than actual discussion of the candidate, you know you have a really, really weak candidate.
I guess this is what happens when the party insiders make the choice, rather than letting the process work, allowing the voters to make the choice. You wind up with a weak candidate.
Their hubris will be their downfall just like last election. They see so much Trump hate on twitter, they dont think they can lose. It's like they dont realize how many Europeans and Canadians are circle jerking online with them while real Americans ignore them.
