Interesting article from the Hill from last December talking about the revolving door phenomenon, and how for the group of congressmen who were recently defeated, the job market will be especially tough:
"The current job market in the influence industry is the toughest in years, several headhunters said, with former lawmakers facing stiff competition for a limited number of high-ranking positions...At least 58 lawmakers will be leaving Congress in January, either because they lost their reelection races or have decided to retire."
The article explains how the congressmen that will be in the highest demand are those that can negotiate with Republicans:
"The November elections also handed defeats to several Democratic senators — Mark Pryor (Ark.), Kay Hagan (N.C.), Mark Udall (Colo.) and Mark Begich (Alaska), among them — whom headhunters say will be valuable because of their reputation as being dealmakers with Republicans."
