Pretty sure Jeb Bush is gonna be the GOP's guy in 2016. It's less than a sure thing that I can back up with real evidence, but more than a feeling (w/ apologies to my loyal fans for dredging up the painful memories of an 80s Hair Band).
Anyway, Bill O'Reilly got after Trump a few days ago, and put up a video clip of Bush (making some interestingly "librul-sounding" counterpoints btw) during his live on-air interview with Lil Donny. This is not something that happens unless Roger Ailes has decided to pass on Trump in favor of somebody else.
Politics is about power, and power is about leverage.
DumFux News (ie: The GOP) knows they have a major problem because of very high negatives and very low positives among Women and Brown People (specifically Latins). They can "win" at the local level and in the state houses because they've done well at organizing their ground game, which gave them plenty of opportunity to take advantage of a little thing called gerrymandering, which then makes for lotsa safe red seats in congress. But there's still the problem of a really low probability for winning the White House for what looks like maybe decades to come.
So what's a good little opinion manipulator to do? Pick a very public fight with the guy who personifies the problems the GOP has with attracting the support of Latins and Fallopian-Americans; do it in prime time with your primest of prime time talent; and be sure to show a good long visual of Jeb Bush sounding reasonable while making just as sure to tell people Donny's positions are costly and extreme: "The guy wants to deport innocent babies and he practically word-raped one of our treasured National Virgins!!! blah blah blah").
Ailes has decided Trump won't be the nominee, so he's setting it up so Fox can present itself to Women and Latins as 'the enemy of your enemy", which (I think) he believes will gain enough support for when he officially throws in with Jeb.
And I think all that because, of course, I'm brilliant. No no no, wait. It's because Ailes knows that Trump's "commanding lead" in the polling actually represents less than 8 or 9% of the total number of people who'll vote in November 2016, and so he believes he can drive the Right Radicals back into the shadows (where he wants them; because while he needs them, he can't afford to have them up front where everybody can see them), AND he can get a Republican elected POTUS in one swell foop.
And also too - I'll try not to be too surprised if I find out that during the "blunt-but-productive conversation" that went on between Ailes and Trump after the Megyn Kelly trouble, it was decided that Trump would at least consider attending to his own skewering by DumFux News in order to get himself a real good deal with whoever "wins" the nomination, and some kind of nice payoff from Rupert as well.
He could win the nomination - not likely, but wow if he does.
He could win the election - very unlikely, buy holy fuck, what if.
He could "lose" either, and still come up roses - highly probable.
Leverage.
Just my opinion, but ya heard it here first, kids.
