Senator John Ensign (R-Nev.) announced his pending retirement yesterday, saying he would not run in the 2012 election. The announcement came to the obvious relief of many of his colleagues – Sen. Ensign is currently being investigated for an alleged affair with a former staffer. But he’s not the only lawmaker planning to sit out the coming election; seven others have also announced plans to get out of politics, or at least, government. Joining us to talk about the other lawmakers who are retiring, and how that may challenge party strategy, is Takeaway Washington correspondent Todd Zwillich.
