According to The Hotline, in Indiana’s 9th congressional district, former Rep. Mike Sodrel (R-IN) "is apparently pondering a re-re-re-rematch with" Rep. Baron Hill (D-IN). "If Sodrel does challenge Hill in '08, it will be the fourth cycle in a row the two have met. More importantly, they have traded victories at least once."
Other former congressmen who are eyeing another run include Jim Ryun (R-KS), Jeb Bradley (R-NH), Joe Schwarz (R-MI), and Rob Simmons (R-CT).
