"Hillary still has a chance, if she can win big in the Pennsylvania primary."

REALITY:  Hillary hasn’t got a prayer.  She will go into the PA primary with a deficit of over 160 delegates, though the exact number varies depending on what source you use.  She could be a big favorite in PA and do really well.  How well?  She got 70% of the vote in Arkansas.  Other than that, her high water mark has been 58% in Rhode Island.   But let’s assume she wins PA with by an astounding 60-40 margin – she will then gain 32 committed delegates (according to Slate.com’s Delegate Calculator) and still trail by about 130 pledged delegates.  Even if EVERY last PA voter goes for Clinton, and she wins the state 100%-0%, she will still trail by 3 or 4 delegates!
