All of Trump's enemies are at least 3 months behind the curve. Think about that and how the race has gone so far. Trump's smarter than his enemies, and he's made them all look foolish. He won't win because of the fact that this matter is decided at a convention. But he won't fade.
Yup, this sums up the situation quite nicely. Trump is keenly aware that he needs to tread lightly for the next few months, and I don't see any chance of his stumbling anytime soon. It promises to be a very interesting convention...
A better question to ask is how it will look when the GOP will look when Trump goes into the convention with the most votes and delegates, but all stops are pulled out to deny him the nomination. What would THAT look like, and what would be the aftershock?
