That is simply n0ot true. He has spent the last few weeks bashing Trump's primary opponents. And why would Trump work so hard to make McCarthy speaker, if he was against him?
McCarthy smelled a rope burn, Nick.
McCarthy’s mouth was full of marbles on Trump, until about 9 weeks ago. KMc spent his Republican Party candidate chatter by avoiding saying Trump’s name, brushing off his early showing with shrugged shoulders, the race was wide open, a deep bench, who knows.
Then he recognized that tiresome tap on his shoulder. Hot seat warming against his performance. He rolled on as Speaker.
The guy realized there is no Republican Party. There is only Trump who is holding the danged thing together.
