Representative Rush Holt (D-NJ), a plasma physicist, didn’t reveal why he has decided to leave Congress after eight terms, or what lies in his future. “This is not the time to discuss next steps in my career; that can come later,” said Holt, who was assistant director of the Princeton Plasma Physics Laboratory before coming to Washington in 1999.
Holt was once part of a triumvirate of Ph.D. physicists in the House. But longtime Representative Vern Ehlers (R-MI) retired in 2010, and Representative Bill Foster (D-IL) returned to the House only last year after losing his one-term seat in 2010.
As of now, I don't see any new blood from the physics community to run for office in the US Congress.
