Capitol Hill can get into your blood. How else to explain the large number of former members of Congress who, for one reason or another, make the trip back, sometimes against long odds. For the 113th Congress, HOH welcomes back nine former members, seven Democrats and two Republicans, who are less likely to get lost looking for the campus subway.

Rep.-elect Alan Grayson, D-Fla.

Turned out in the 2010 GOP wave, the boisterous lawyer who described Republicans’ health plan as “die quickly,” returns to the waiting cable news standup circuit.

Rep.-elect Bill Foster, D-Ill.

Congress doubles its number of physicists with Foster’s return. The average IQ goes way up when he walks in a room.

Rep.-elect Ann Kirkpatrick, D-Ariz.

We love the fact that someone who speaks Navajo, the language that helped win World War II, is back in town.

Rep.-elect Dan Maffei, D-N.Y.

Maffei, a former senior aide to Rep. Charles B. Rangel, D-N.Y., is another member with a staffer’s viewpoint.

Rep.-elect Rick Nolan, D-Minn.

Nolan left office in 1981, a long time to be away from the Capitol, so everything should be fresh for him. He was born in Brainerd, Minn., an important plot element in the classic film “Fargo.”

Rep.-elect Matt Salmon, R-Ariz.

Salmon, who left under self-imposed term limits in 2001, is back for a second stint. He speaks Mandarin and has a degree in literature, so he brings some intellectual heft to the class.

Rep.-elect Carol Shea-Porter, D-N.H.

Maybe this time around, we can coax Shea-Porter to tell us her birthday, which she keeps private. We just want to send a card!

Rep.-elect Steve Stockman, R-Texas

Stockman was part of the iconic freshman class elected in 1994 and looks to be someone who will carry the no-holds-barred conservative torch, just in case anyone starts thinking about cutting deals.

Rep.-elect Dina Titus, D-Nev.

Titus returns after being turned out in the 2010 GOP wave and now represents America’s adult Disneyland: the Las Vegas Strip.
