“I’m going to take it easy,” said Rep. Barney Frank, who’s been running for the past 40 years.

Any regrets? None, Frank told us. “I haven’t got the emotional energy to do the job the way I want to do it.” Instead, he’ll write books and become a public policy advocate.

After 16 years on the Hill, Rep. Dennis Kucinich isn’t on the ballot— but “I haven’t really noticed, because I’m a man in motion,” he told us Tuesday.

Sen. Joe Lieberman, who joined the Senate in 1989, skipped politics altogether: He spent Tuesday speaking to the Connecticut Technology Council. “He’s approaching it as a private citizen, at least as far as the election goes,” said his spokesman.

Sen. Ben Nelson spent the day back in Nebraska after endorsing Democratic candidate Bob Kerrey, who’s running to fill Nelson’s vacant seat.

Which brings us to our final point: Never say never. After a distinguished political career, former senator Kerrey called it quits and went into the private sector — relocated to New York, settled into marriage and fatherhood, served as president of The New School. But Nebraska politics called, and Kerrey moved back home after a decade — despite objections from his very East Coast wife.

So it was probably no surprise that Joe Biden is keeping his options open. The vice-president met with reporters in Delaware after voting early Tuesday morning — the eighth time he’s cast a ballot for himself in a statewide election. Last time?

“No, I don’t think so,” he said with a big grin.
