If I've done the math correctly, Hillary only needs 5.9% to win the party nomination.
According to the NYT website, here are the current breakdown of delegates:
Obama: 1913.5
Clinton: 1715
There are 373.5 delegates (elected and super) left unapportioned. For the moment let's assume that half go to each candidate:
Obama: 2100.25
Clinton: 1901.75
Now, Hillary only needs 2026 delegates to win. You can see she is only 124.25 delegates short of this number. That is the number of delegates (pledged and super) who need to switch from Obama to Hillary. 124.25 is only 5.9% of Obama's 2100.25 delegates.
I hope this shuts up everybody who says there is no mathematical way for Hillary to win.
P.S. - After further analysis, I realize that Hillary is actually only five votes away from the nomination. (See
