I’ve actually just did a little research on Sasse to determine where and when he turned against Trump. Apparently he was never really in his corner at the beginning....saying that he would not support Trump should he become the party’s nominee.... Sasse also suggested, at that time, that he could leave the Republican Party,... “if the Republican Party becomes the party of David Duke, Donald Trump, I’m out”..... And yet he’s supported all Trumps agenda while he was in office.
So it appears to me he simply doesn’t like Trump and doesn’t want him back in office at any time in the future.
Sasse is an opportunist, a climber. Sasse’s character is very much typical of the narcissistic elitist mentality one discovers in the “churches” of academia. I consider Sasse as nothing more than a patronizing condescending BS artist, who looks down his nose at us “plebes,” while he lectures us on the Constitution, and pretends to be just another western “country boy.”
Senator Sasse has his eyes on the presidency, always has, - and he wants Trump out of the way.
