If this claim is going to be made, there should be some accompanying data to back it up, such as determining what her endorsement is worth in terms of votes. Endorsing winners does not translate into being a kingmaker; it may mean you just backed the right horse, like Orrin Hatch for example.
She’s pretty close to batting 1000 this cycle and many of those candidates had little or no chance (Mrs. Fischer, Mr. Cruz, etc.) until she appeared, but you can go on saying that she was “just lucky” and all, most of us know political genius and charisma when we see it. I keep being amazed by the PDS on what is claimed to be a conservative site. Or do you simply have a problem with strong women? If I’m mistaken, I apologize in advance, but the sexism on here sometimes astounds me.
Perhaps you haven't really been paying attention since Palin began endorsing (and working her butt off for) conservative Tea Party candidates. Her win/loss ratio falls far outside the realm of mere chance.
She's the E.F. Hutton of Republican politics.
