USA Today Online is featuring an interesting article about "Comeback Kids" — referring to Members of 
Congress who leave the institution (for one reason or another) and then come back. One example, referenced in the story, is California Republican Congressman Dan Lungren, who left Congress when he was nominated to be State Treasurer in the ’90’s. While that didn’t work out, Lungren went on to be elected State Attorney General, and was the party’s ill-fated nominee for Governor against Gray Davis in 1998.
The article talks about two more Californians attempting their comebacks — former Congressman Brian Bilbray is running in the donnybrook to succeed the disgraced Randy Cunningham — and up in the Central Valley, former Congressman Pete McCloskey is in an uphill Republican primary against popular Representative Richard Pombo.
