The list of House Republicans who may retire in 2008 is an expansive one, indeed. One name that I've heard a substantial amount of buzz surrounding is Rep. Dave Hobson of Ohio's 7th. Unverified rumors claim that he will likely retire, but one local blogger is already calling it a done deal:
The much expected retirement of Cong. Hobson has not been formally announced even though State Senator Steve Austria (Hobson’s hand picked successor) is already preparing for a Congressional campaign and at least two Repuiblicans are lining up for Austria’s Ohio State Senate seat.
With a PVI of R+6, Ohio's 7th has a pronounced Republican lean. It twice supported Bush by a 14-point margin (56-42 and 57-43, respectively), but much has changed since 2004 in national and state politics since 2004. I expect a good number of lean-Republican seats to come open in 2008 (Hastert in IL-14, LaHood in IL-18, and Regula in OH-16 for instance). If Van Hollen can deliver some solid recruits, I suspect that we may be able to pick up a couple.
