According to the Associated Press, Barack Obama has 1610.5 pledged delegates awarded in primaries and caucuses (i.e. not counting the superdelegates). Hillary Clinton has 1443.5 pledged delegates.
There are a total of 3,253 pledged delegates available - and Obama needs just 17 more to win a majority of those pledged delegates. There are 51 pledge delegates up for grabs in Kentucky, and 52 in Oregon today.
Notwithstanding the question of the superdelegates, if Obama gets 17 more delegates today (as he should, barring a meltdown), should he declare victory?
