I read that Jeb Bush's speech and performance, the Q&A at the Council on Foreign Relations was not inspiring.

At 57 per cent among Republican primary voters, he is way ahead of Jeb (37 per cent). Although Jeb leads marginally in voters’ first preference, Rubio tops the second-choice rankings. In a fragmented field, that could count for a lot. Finally, Rubio is neck-and-neck with Jeb in the key swing states, including Ohio and Florida, and comes closest of any Republican to defeating Hillary in a head-to-head match-up.-The story behind a Rubio campaign video that the campaign didn't make
