Trouble between Miller and Palin?

Questions are being asked about Joe Miller's interview with Neal Cavuto the other day and his lack of endorsing Palin as a viable candidate for president. This source over at the Huffington Post is highly unreliable:

An irate email written by Todd Palin seems to confirm his wife's presidential ambition, and revealed his anger at Alaska Republican Senate candidate Joe Miller. The email demands that the treasurer of SarahPAC, Tim Crawford, "hold off on any letter of support for Joe," and came on the heels of an interview Miller gave to Neil Cavuto on Fox News Sunday.

Not surprisingly, Conservatives4Palin has a response:

Desperate for some traffic, Mudflats has released e-mails that she purportedly has acquired from Todd Palin and Joe Miller. Assuming that the e-mails are valid, what's exactly wrong with the substance of Todd's e-mail?

What we learn is that Todd Palin wants Joe Miller to endorse Governor Palin's run for the presidency. Why is anyone shocked that Todd would want a candidate to endorse his wife?

Some suspect that Huckabee backers were responsible for the leak of the emails. Over at The Other McCain:

“This is the worst sort of betrayal I’ve ever seen,” one source close to Sarah Palin said in describing the leak of an e-mail that Todd Palin sent to Joe Miller, the Alaska GOP Senate candidate.

The source noted that some of Miller’s campaign staff have connections to 2008 Republican presidential candidate Mike Huckabee, and suggested that these staffers have been advising Miller to distance himself from Palin.
