Will an Establishment or Insurgent candidate be nominated by the GOP?

[Mordecai]

The nominee in 2016 will be another establishment candidate.

The establishment of the party, represented by folks like Romney, Rove, and the Bush family, are still searching for a suitable candidate. Meanwhile, the Jim DeMint-wing of the party is flush with money from the Heritage Foundation and Sheldon Adelson (among others) to mount a serious "outsider" candidacy. Is this the year that an insurgent candidate breaks the cycle, or will the 2016 be another coronation process?

Adelson learned from his mistake and is looking to finance someone from the establishment who has a chance of winning, somebody like Bush, Christie, Walker, etc.

One problem with Insurgents is that the grassroots will have different ideas on who the best candidates are. If Huckabee, Rand Paul and Ted Cruz all run they'll have appeal to different segments of the party. For much of the race, each is likely to have a floor, but that comes with a ceiling.

The establishment is likely to coalesce around whoever is doing better in the early primaries among the candidates who are broadly acceptable to them.

Adelson also saw Gingrich as establishment enough, due to his previous experience as Speaker of the House. Gingrich wasn't Herman Cain as much as he pretended otherwise.

You're missing the point that he has obviously learned from that mistake. He invited Bush, Christie, Kasich and Walker to meet him at his hotel, all of whom are both establishment and reasonably electable compared to Gingrich.
