Sen. Johnson: Not A Stroke?

Political blogs and websites virtually exploded this afternoon when news surfaced that Democratic Senator Tim Johnson of South Dakota had possibly suffered a stroke.

Balance of Power Hangs in the Balance?, blared the headlines.

But now word from Johnson's spokesman that the Senator did not in fact suffer a heart attack or stroke.

So which is it?

And does power still hang in the balance?

By the way, journalistically I understand why it is natural to talk about the potential political implications. But for some reason I feel like we should all hang back a bit and hope the guy is ok first for the sake of his family and friends before we begin pontificating.
