The premise of Jeb was inevitability and predictability.
Trump has shattered those premises. Even if Jeb emerges the nominee (and it’s still likely) much like the boomlets for Cain, Santorum, and Gingrich demonstrated in 2007-2008 a deep ambivalence about Romney, Jeb’s poll standings show he’s very unlikely to provide the electricity needed to pull the Electoral College inside straight any Republican needs to win in November.
A lot of people will pay for access to the next President. Not as many will pay for backstage passes to a polite concession speech in a Miami ballroom.
Likely: having a high probability of occurring or being true : very probable
Really?
You are correct. The Mitt Romney party rules changes in 2012 made it a very uneven playing field.
Bush could lose the nomination and still be the nominee.
