But it seems like most everyone agrees that their convention was a debacle. I don't know any Pubs who were like, "Yeah, this kicks ass". Most were cringing at the lineup and all the plagiarism. And then what happened with Ted Cruz. JHMD might be right about casual followers of politics being surprised by how much they agreed with Trump's speech. It might be why, even though he's a terrible debater (worst I've ever seen) he comes out of the debates against Hillary okay.
Apparently the "biggest de-bacling in the history of debacled" conventions gets the standard 4-5 convention bump. No reason to expect consistency from the people who supported Sanders and Clinton in the same election.
