The Edwards Endorsement: Senator Clinton...last night she won the what in the where, now? Our fifth story on the Countdown: the polls have now closed in the State of John Edwards: Senator Obama tonight winning the Edwards endorsement by a margin of 100 percent. And 24 hours and 30 minutes after voting ended in West Virginia it, and perhaps Senator Clinton herself is old news.

About Last Night:  It was not supposed to happen this way. On this, the day after, Senator Clinton was supposed to ride the momentum of her resounding victory in the West Virginia Primary... in a parade of interviews on all of the networks... making her last, best case that she -- and not Senator Obama -- would be the more "electable" candidate against John McCain. In our fourth story on the Countdown: -- continuing our breaking news coverage -- that all changed at 5:12pm Eastern... when the first bulletin crossed the wires... confirming that Senator Edwards would be backing... Senator Obama. Something tells us that the disappointment of the loss will not keep Senator Clinton from continuing to make her case that she should be the Democratic nominee... as she did to our colleague Brian Williams this afternoon...before word of the Edwards endorsement broke.
 
The GOP Horserace:  If you think the Democratic Congressional Committee Chairman overstated it by saying that "there is no district that is safe for Republican candidates." What of a Republican congressman's reaction...Tom Davis of Virginia, stamping his feet on the floor of the Capitol basement today. Quoting -- "This is the floor. We're below the floor." In our third story on the Countdown: last night's special-election victory by a Democrat... in a Mississippi district so heavily Republican that President Bush carried it by 25 points in 2004. With the GOP's attempt to win by running against Senator Barack Obama and Jeremiah Wright -- in a race-baiting manner -- failing.
