PA 8 and PA 4 should be included, too.
And let's not forget the other potential rematches:
CA-04 Charlie Brown has announced his candidacy again but it is less than sure that Rep. John Doolittle will remain the GOP nominee when the 2008 election comes around.
ID-01 Larry Grant seems to be considering another run but he appears to face competition. Meanwhile, the unloved Rep. Bill Sali may face primary competition again.
FL-13 Of course, Christine Jennings is running again against Rep. Vern Buchanan who was elected because of voter error...
NC-08 Larry Kissell who barely lost to Rep. Robin Hayes has said he is planning to run again.
NH-01 Jeb Bradley may try to get his seat back from Rep. Carol Shea-Porter.
NJ-07 Though state Rep. Linda Stender has not said a rematch against Rep. Mike Ferguson isn't a sure thing, it seems to be strongly under consideration.
NY-25 Dan Maffei announced he is again challenging Rep. James Walsh.
NY-29 Eric Massa is seeking a rematch against Rep. Randy Kuehl but has to get past an announced primary challenger first.
WA-08 Lackluster Dem Darcy Burner thinks she can ride Presidential coattails against Rep. Dave Reichert. I hope some other Democrat who has a chance is the nominee.
WY-AL Gary Trauner may again seek to oust Rep. Barbara Cubin.
