Obama and Clinton pick up one pledged delegate each from the finalization of delegate counts. (CNN's Delegate Page does not make it clear which states these 2 delegates are from.) In addition Obama picks up two more superdelegates. Net result, Obama further expands his lead by 2 delegates.
The day before Clinton's "big wins in Ohio and Texas" Obama was ahead by 102 delegates. Obama is now ahead by 139.
Right now Clinton needs 58.6% of the remaining 918 delegates to win. Obama only needs 43.5% of them.
She will close the delegate gap somewhat in Pennsylvania. But it is unclear if she will actually be able to win by a big enough margin to be on the 58.6% pace she needs to actually win. If she gets less than 58.6% of the delegates in PA, then after PA she'll actually have a harder road to the nomination than before, not an easier one.
When you are behind, running faster is not good enough. You have to run fast enough to catch up.
(Let alone running slower, which is of course what she has done so far.)
