McCain's Office Not Saying Who He Supports In NY-23

Here's an important question on the NY-23 race: Now that the Republican Party's 2008 Vice Presidential candidate Sarah Palin has broken with the party to support a third party Conservative over the moderate GOP candidate, who does her former running mate and ex-presidential nominee John McCain support?

I have placed multiple messages with McCain's office, asking which candidate he supports in the special election, and whether he agrees with Palin's denunciation of the GOP for putting up a moderate nominee. They have not gotten back to me.
