One senator who has an opportunity to burnish his conservative credentials in Spectergate is Ohio’s Mike DeWine, a Republican member of the Judiciary Committee who is not a reliable conservative vote on all things. He is exactly the kind of senator who has to worry about a GOP primary challenge from his right — say, from a figure such as Ken Blackwell. DeWine is up for re-election in 2006, so now is not too soon for him to demonstrate conservative leadership and say he doesn’t want Specter chairing the Judiciary Committee.
