The notion that Mary-Ann Conway/Fitzpatrick a saboteur for the GOPe is ridiculous. Frankly, I can't be sure whether the author is just too paranoid, or playing for the other side. (Btw -- How many folks here at one juncture or another were supporting Cruz? Yes, JUST like Mary-Ann? Just sayin'.)
Mary-Ann Conway/Fitzpatrick is yet and still on OUR side: TRUMP'S. Her job has always been to gauge how best to frame her GOP candidate as best as she could as a professional political consultant. Before Trump shook things up there were only the DEMS or GOP for whom to work.
Anyone who witnessed her CNN/Don Lemon mugging under fire noted that she was poised, well-reasoned, and was able to hold her (Trump's) ground.
