Think of it this way. If Trump hadn’t gotten out there last summer and did everything it took to rattle the cage, Jeb would’ve had it sewn up before all but a few political nerds were paying attention. He had already locked up the deep-pocket donors and the insider vote.
That's still what shocks me. Jeb had the nomination all but secured before Trump appeared. Even Cruz has benefited - no way would be be in second place now if Bush were leading.
