Sen. Tim Johnson hospitalized

The Democrat reportedly suffered a stroke.

I'll get into this in more detail later as time and information allow. Beyond the personal implications for Johnson and his family, if he is unable to serve his replacement will be named by the state government, which is dominated by Republicans. That would probably lead to a 50-50 split in the Senate, which would throw control of that body back to Republicans thanks to the vice president's tie-breaking vote.

Just when you thought it was over....

Update: As the commenter noted, it wasn't a stroke and doesn't appear to be serious -- although they're not saying what it was.

Update II: Johnson is now in critical condition after brain surgery. The problem was a "congenital arteriovenous malformation", which causes tangled blood vessels.

The surgery was apparently successful and the prognosis is good.
