Why would she endorse anybody? She said she has a great gig, she says things and the next day all the candidates are adopting her position. She endorses one, and the others stop listening.
If she doesn’t run, I don’t expect her to endorse anybody. She’ll keep critiqueing them, trying to get them to change for the better, and she’ll find candidates across the country to support, she’ll raise an army and send them to congress.
I've liked Sarah Palin, but I heard her say that and found it somewhat unbecoming.
