I have been hearing a lot of static noise about who may be considering a run for the State Party Chairman. This may not be breaking news, but it appears that Matt Salmon will not be seeking a new term at the convention in January, so ostensibly, the post will be wide open.
To my knowledge, however, the only sure candidate at this time is Randy Pullen. Nobody else is stepping forward publicly right now.
If you were the gambling sort, I would look for another candidate to come forward under John McCain's banner, as I do not believe Pullen is McCain's man. McCain will need that extra support of the State Chair, especially if Mitt Romney continues to build momentum. With his LDS background it is possible that Romney could manufacture a sizable ground game in short order to compete for Arizona's electoral votes in the Primary.
This is not to say that there is any connection between Pullen and Romney, or any of the other possible Republican presidential candidates, for I do not believe there is. However, McCain will want to lock down the state party as soon and as comfortably as he can, and this may not be possible with Pullen in charge.
