Palin's support of Trump is wholly in contradiction of everything she claimed to support when she was running for V.P., then President (but then, not really - just the pretty bus tour, reality shows, and media contracts).
Logically, this means that she did not originally believe what she was saying. She validated the worst of what the RINO's and progressives claimed about her, and her family (i.e. namely, her repetitively unchaste daughter). Namely, that she was an opportunist. Whether her original goal was power, fame, money, or a combination of the three, it wasn't conservative and Christian principle.
You betcha, that dog won't hunt.
I say this as one of the most diehard supporters of hers, who even gave her a pass when she initially supported Trump over Cruz. I reasoned that she and her family had been so "sh**t on" by the RINO's, that taking a Trump wrecking ball to the GOP-e might be an understandable, if sad, reaction. However, when she kept partying-on on the Trump train, even after Trump's abuse and lies about Cruz and other conservatives she previously supported, it was clear that she is simply, like Trump and many of his supporters, amoral. She has a certain set of personal values, which may comport with "Christian" or "conservative" principles when it suits her, or they may comport with progressives, Alinsky, or Machiavellian principles, when she feels so entitled.
She's an amoral opportunist, and her "rambling" speeches reflect an unmoored, unprincipled, lost soul. As a Christian, I pray for her. As a patriotic American, an oathkeeper who has never violated or recanted his oath as a Naval Officer, I detest her.
