As we have known for a while, May 20th is the day Obama will officially win the primary. With 1599.5 pledged delegates after yesterday's primary in West Virginia, Obama is 27.5 away from the 1627 he needs to have a majority of the 3253 pledged delegates.
Even if he performs even worse in KY than he did in WV (only 20% of the vote, for example), that should net him about 10 of KY's 50 delegates. Even if he barely wins OR and Obama and Clinton split the delegates (he'll do much better than that), that would be 26 of OR's 52 delegates, which will put him well over the hump (with PR, MT, and SD yet to come).
Clinching the pledged delegate lead will bring over the "Pelosi club" of super delegates who have pledged to support the pledged delegate leader. DemConWatch counts this as a gain of 7 for Obama and loss of 1 for Clinton, but that should be the floor not the ceiling for superdelegate commitment on May 20th -- the Oregon win and the pledged delegate clincher should provide plenty of cover for superdelegates to come on over. Not that they need much more incentive to come on over after the Republican effort to tie Obama and Wright to Childers worked out so well . . . for Childers!
Anyways, let's plan a big celebration for May 20th and push those "Obama Wins!" stories into the press yet again. And he can "Win!" again when he crosses the 2025 mark and we can celebrate that as well. Maybe even one more time when he passes the Clinton camps' 2209 figure. Can't have to many opportunities to present Obama as the winner in the national press, can we?
