The Cook Political Report put four more incumbent House Democrats on notice Monday -- adding them to its very large Toss Up category.
Cook has moved Democratic Reps. Chellie Pingree (Maine), Jim Oberstar (Minn.), Mike McIntyre (N.C.) and Rick Boucher (Va.) into the toss up column. It has also moved Rep. Michael Michaud (D-Maine) from Likely Democrat to Lean Democrat.
These ratings changes show the rapidly widening play field for the GOP. Michaud was well off anyone's radar screen two weeks ago, as was Pingree.
The Cook Political Report has also moved several Democrats from Toss Up to Lean Republican, a sign that their chances on Tuesday are slim. They include Reps. Frank Kratovil (Md.), Dina Titus (Nev.), Harry Teague (N.M.).
