I have always suspected so. It was absolutely a grand endorsement. He was ambivalent about Trump crediting him for showing GOP does NOT have to be afraid of and pander to the media. Very kind to Carson, finally saying Carson versus Hillary or other dems, yeah he would vote for him and he could not be less qualified than the dems.
Surprised not asked about the rube. Wallace is also obviously the one who asked the show be taped so he would not get a gazillion emails about him interrupting Rush, lol. Rush looked really good, healthy.
Rush has criticized Rubio on some of his positions and hit him late last week for Rubio’s criticism of Cruz for supporting the USA Freedom Act. I think Fox was trying not to give Rush an opportunity to criticize Rubio.
