Challengers Lining Up for Incumbent Dem Senators

2012 promises to be another tough year for Democrats in Congress (from Political Wire):

After the announcement that Rep. Denny Rehberg (R-MT) is planning a challenge to Sen. Jon Tester (D-MT), Alex Burns notes that there are now four 2012 races where Democratic incumbents face "high-profile, formally announced challengers," the exact number that Republicans must win to reclaim the Senate.

The four: "Montana, Missouri (former state Treasurer Sarah Steelman), Nebraska (state Attorney General Jon Bruning) and Virginia (former Sen. George Allen)."

Kicker: "That's not to mention the open Senate seat in North Dakota, where Democratic Sen. Kent Conrad's retirement gives Republicans a strong pickup opportunity, and Florida, where several solid candidates are circling the race against Democratic Sen. Bill Nelson." 

I see another busy election night coming.
