Simcox vs. McCain - Who will Palin endorse?

In his campaign kick-off for U.S. Senate against John McCain, Republican Chris Simcox admitted Wednesday that he cast a ballot for McCain in November for president.
So, Simcox thinks McCain was fit to lead the free world but not represent Arizona in the U.S. Senate?

“I had no choice,” Simcox explained of his vote. “Let’s say Sarah Palin was acceptable, and that's who I voted for.” - http://www.azstarnet.com

The big question is who will Palin endorse and will the fact that McCain has not been outwardly supportive, sometimes even "forgetting" to mention her (but maybe that could have just been one of those senior moments *wink) , play any role in her choice.
