Does anyone stay in after this?

Watching politics as long as I have, this is a big deal,

Clinton will huddle with advisers and husband Bill Clinton at her mansion tomorrow, according to people familiar with her plans. She will monitor results from the final 2008 primaries in South Dakota and Montana and decide whether, how and when she will end her campaign as Barack Obama nears the nomination threshold.

This certainly doesn't mean she drops out tomorrow, but nobody ever emerges from their "huddle with advisers" to declare victory.
