180s in short order are not without precedent. the GOP was once the liberal progressive party for old time standards and the Dems were the party of slavery and confederacy. But that's an extreme example. A more recent example is how the TrumpGOP views overseas intervention and wars vs. say the Reagan/Bush era brand of GOP.
At least Trump gets to play golf now. Obama spent 8 years from 2009-2017 playing golf more than being president. Well at least he didn't have his VP and redhead be his mouthpiece. Jay Carney and Josh Earnest were ditzes but nothing like now.
