Vacant Lott

Politics | No. 2 Senate Republican becomes No. 6 to head for the exit door. Why the GOP exodus? | Jamie Dean

The wintertime departure from Congress of Sen. Trent Lott is heating up a political environment already stickier than Mississippi in summertime.

The second most powerful Republican in the Senate announced on Nov. 26 that he would resign his Mississippi seat by the end of the year, stunning even close advisers: Lott was just one year into the six-year term he won by reelection last November. He has served in Congress nearly 35 years.

Lott is the sixth Republican senator to announce his retirement this year. In the House, 17 Republicans have said they would leave. Lott's retirement plans raised immediate questions: Why is he leaving? Who will replace him? And what will a slew of Republican retirements mean for a fragile congressional balance during next year's elections?
