@snood,
The Koch brothers' gang said about a year ago that they didn't like any of the other candidates in the Republican race and were willing to let this round go to Trump while they worked on developing candidates for the future (ask georgeob what the rich, old, white guys are doing in the redwoods with the Koch boys this weekend).
Media that wants to stay on the right/correct side of the Koch organization would of course help Trump's momentum.
Nothing surprising* in that world has happened since the last meeting in the redwoods (if you follow that group).
* with the exception of the possible derailment of Ailes
