Reps. Dan Burton (R-Ind.) and Mark Souder (R-Ind.) emerged from Tuesday’s primaries bruised but unbeaten. Their performances, however, won’t do much to hearten members worried about their own primaries.

So, as we talk about this pervasive anti-incumbent mood, who’s next? In fact, several other members of Congress will learn their primary fates in the coming days and weeks.

The Ballot Box looks at incumbents who could fall in the next month:

Saturday – Sen. Robert Bennett (R-Utah): The three-term senator has turned into an underdog at his state party convention this weekend, and recent polls suggest he might not even make the final ballot at the convention, which would effectively end his tenure in the Senate.

Tuesday – Rep. Alan Mollohan (D-W.Va.): Mollohan faces state Sen. Mike Oliverio, who nearly outraised him in the first quarter and led him 41-33 in an internal poll two weeks ago.

May 18 – Sen. Blanche Lincoln (D-Ark.), Sen. Arlen Specter (D-Pa.) and Rep. Paul Kanjorski (D-Pa.): Could two Democratic senators fall on one primary day? They could. Both Lincoln and Specter have seen their leads shrink to single digits. The most vulnerable man that day, though, might be Kanjorski, who faces Lackawanna County Commissioner Corey O’Brien.

June 1 – Rep. Parker Griffith (R-Ala.): Much like Specter, Griffith is dealing with the aftermath of a party switch. He went the other way, to become a Republican, and the GOP primary never cleared. Madison County Commissioner Mo Brooks and businessman Les Phillip will battle with Griffith over who is the real conservative Republican in the race.
