These Republicans are like the Japanese on the island who still think WWII is in progress. Her brand of Republicanism is obsolete. I mean just look at Nikki Haley. She thought she could do the usual swamp Republican move where she disses Trump and then quietly tries to worm her way back in.
Trump's biggest legacy was ripping off the phony facade that was the 2 party system.
These foolish lifetime politicians are totally divorced from anything that isn't their traditional political theater. They are incapable of seeing that trump is not a machiavellian political power player. He is a deal maker. To make deals you need people who (1) can be relied on to do what they promise and (2) don't cheat or double-cross you. That translates to people who are trustworthy, loyal, and honest. Sadly such types are almost entirely absent in DC, to the extent that swamp creatures don't even understand that such people can exist.
Taking a job from Trump, then later trashing him, and then asking for his support is the epitome of someone who has no loyalty or honesty. He seems to forgive a single lapse but multiple ones get under his skin quicky. She took it too far.
