Congress will get back to work on Tuesday, but the structure will be different than it was last year. The Republicans control the Senate now, led by Tennessee's Bill Frist.
Frist will now be in charge of pushing the GOP agenda through Congress, instead of Mississippi's Trent Lott.
"Bill Frist is not a person who's deeply experienced in the ways of the Senate, of getting things through, but he's going to have a lot of help," said Steven Hess of the Brookins Institute.
Lott is not completely out of a leadership role. The Senate's third ranking Republican, Rick Santorum of Pennsylvania, is stepping aside for Lott to chair the Senate Rules Committee.
