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.
She didn't endorse Cruz until mid-May, and by that time, she was not decisive in getting him into the run-off (an April poll already showed Cruz in a position to make the run-off). And by the time she came to TX during the run-off, the polls showed Cruz with a big lead. Cruz, his campaign, and their volunteers were the kingmakers, not Palin. I won't speak to Fischer, because I don't know anything about her race, but I'd be interested to see any actual numbers which showed the endorsement as moving votes in such a way to make Palin a kingmaker.
I don't think endorsements matter much in an election, whether that endorsement is Palin's, Rick Perry's, etc., et al. What matters is getting votes. If you or anyone else has any thing that shows these endorsements move votes in such a way that they have more impact than direct voter contact by the candidate or their campaign, then please share it. Otherwise, I'll stick with the understanding that while endorsements generate earned media, the endorsers are not kingmakers.
