The progressive website Calitics notes a poll on DailyKos about Boxer vs. Schwarzenneger in 2010 and then declares:

"Actually, the huge mistake of this poll is not running numbers on the guy who's going to actually be the Republican nominee, Chuck DeVore.  He just secured the endorsements of practically the entire GOP State Assembly and over half of the GOP partisan officeholders in the state.  And it's January '09.  There is no chance that Arnold Schwarzengger, loathed by his base, can beat DeVore in a closed primary.  None.  Ain't gonna happen.  There's only one head-to-head worth polling, and that's Boxer/DeVore.  Poizner and Whitman are running for Governor.  The field is cleared."
