The state of the race at this point is as follows.  Sen. Hillary Clinton needs 171 of the remaining 189 pledge delegates to overtake Obama’s lead.  That means that Clinton will need 91% of the remaining pledged delegates to secure victory.  Broken down even further, Clinton will need to win 91% of the vote in every remaining state including Puerto Rico.  Side point about Puerto Rico: it cannot vote in the general election so it does not help Clinton’s argument that she is more electable in the general election even if she wins it in the primary.  Back to the facts.  Given that Obama has a significant lead in Oregon right now of an average 52% to Clinton’s 35%, he will at least net 26 delegates of the 52 delegates being allotted.  Currently Obama enjoys a 153 pledged delegate lead over Sen. Clinton.  Obama only needs 19 delegates to win the insurmountable majority of the pledged delegates.  Because the majority of superdelegates agree that overturning the collected will of the people would be disastrous for the party, Obama basically clinches the nomination on May 20th, the night of the Kentucky and Oregon primaries.  Looks like that is all she wrote.
