I want all of these news stories to cease and desist until Clinton actually concedes. :) Geesh.

Not a slight to jon but a slight to the news folk.

Does anyone else think that this would be a prime time for McCain to announce his running mate?

No-But it would have been prime time for Clinton to very gracefully bow out of race.
I do not understand to game of political poker she is playing at all.
Rather that unite her party in one night, she chooses to drag it out for a few more.
IMVHO, she is going to wait a few days to give her supporters time to vent and cheer her on and then bow out and give her full support to Obama.
At least I hope that is what she does.
Time will tell.
