Teddy is doing better today, apparently:

"I feel like a million bucks. I think I'll do that again tomorrow," Kennedy quipped to his wife, Victoria, after the 3 1/2 -hour surgery, said Stephanie Cutter, a family spokeswoman.

The surgery was "successful and accomplished our goals," neurosurgeon Allan H. Friedman, who performed the operation at Duke University Medical Center in Durham, N.C., said in a statement.

While another old Dem Senator isn't feeling quite so well:

Sen. Robert Byrd (D-W. Va.) was admitted to the hospital for the third time this year on Monday night, this time for overnight observation after suffering a high fever.

Byrd, 90, the longest-serving senator in U.S. history, was taken to a Virginia hospital in the early evening and will stay there overnight after feeling ill throughout the day, spokesman Jesse Jacobs said. Jacobs said Byrd had felt “lethargic and sluggish” throughout the day, but attended the lone Senate vote of the day, at 5:30 p.m.

So it goes.
