Three prominent Democrats have announced that they are not going to be running for their seats this year. Sen. Byron Dorgan, D-N.D., said he wanted to write books. Sen. Chris Dodd, D-Conn., told reporters it was just time for a change. Moments later, Colorado Gov. Bill Ritter announced that he would drop out, because he wanted to spend more time with his family. What each incumbent hinted at, but left unsaid, was that they were facing long odds in their upcoming races. Ritter and Dorgan didn’t even have announced opponents, but still trailed prospective rivals by 8 and 20 points, while Dodd trailed Republican Rob Simmons by about 10 points.
