This will probably be my shortest diary to date, but I thought it was worth pointing out. Before the Puerto Rico primary, Hillary Clinton needed 79.24% of the remaining delegates (uncommitted + edwards delegates) in order to claim the nomination. She had 1876.5, and there were 303.5 remaining delegates. She needed 79.24% of them to reach 2117.
Now, after winning Puerto Rico, she has 1914.5 delegates, with 248.5 remaining. She now needs 81.49% of the remaining delegates. That's a higher percentage than before winning Puerto Rico. She got a lot today, but she didn't even get the bare minimum to hold steady. She fell further behind today - her nomination is even less likely than it was before.
