Curious question: how bad are Bachus' opponents relative to his own politics? Because I have a sneaking suspicion he's on the curb, after the anti-incumbent primary tear the conservatives went on last cycle.
Both his opponents are running to his right.
State Senator Beason: He was the chief sponsor of Alabama's version of the AZ-style immigration bill and has a record of proposing "English language only" legislation. His campaign website has a Gingrich-style "plan" for cheap gasoline and attacks Bachus for supporting TARP and such.
Blount County Probate Judge and Commission Chairman Standridge: (yes, apparently he's the county's executive and judge at the same time, I had no idea any states allowed that) He's running as more of a deficit hawk, it seems, but still conservative as all hell (for example, a brief scan of his campaign website reveals that he's against abortion in all circumstances, no exceptions).
