Watching Morning Joe today and Joe and some others were pushing the theory that Trump is a genius and this is all part of an elaborate plan. Trump letting the Melania story fester was on purpose to create more buzz. Putting Cruz out there to not endorse was all to help unify the party with hate for Cruz and sympathy for Trump. It was all based on the notion that any press is good press.
Not sure I buy that theory. Others in the show, notably Halperin and Heilemann weren't buying it. Although Halperin pushed the 'Trump can turn it all around with a good speech and that is all anyone will remember' line.
I don't buy the Trump is a genius part, but I do think his actions are often best explained by the notion that any press is good press. Unfortunately for him, that's not a good strategy for a political convention. Messaging matters, and the plagiarism and Cruz non-endorsement distracted from it.
It does make tonight's Trump speech must-see-TV. And a good speech can easily save the convention.
