There really is ZERO excuse for her to endorse Trump at this early stage in the primaries with real conservative candidates with a real shot in there fighting for the nomination. The Cruz campaign must know she’s going to endorse Trump for them to react this way. And Bristol Palin’s response to the Cruz campaign has “My Mom Will Be Endorsing Donald Trump” written all over it. If Sarah Palin goes through with this, it will be viewed as a HUGE betrayal (that she will never recover from IMHO).
I don't think that's true. She's been clear for a long time that she liked them both. If she picks one she thinks will be the better candidate, only those who demand she should have picked their preferred candidate will see it as a betrayal.
