Predictions

Obama has failed in blowing out Clinton in NC, so he won't make up Pennsylvania, but he will come out of the night with more delegates and a gain in his popular vote lead. Pollster has Clinton up by 4.4% in IN, and Obama up by 7.8% in NC. Since the NC trend has been down for Obama, and Indiana has stayed fairly steady, these might edge closer -- say 5 for Clinton in IN, and 6 for Obama in NC -- but there's no reason to think Clinton's margin in IN will be larger, percentage-wise, than Obama's in NC, since every poll has shown Clinton stronger in IN and Obama stronger in NC. Plus, once you factor in the state sizes, it's not close. IN has 72 delegates, NC has 115. 115/72=1.58, so Clinton has to win IN by something like 1.5 times Obama's margin of victory in NC -- a 4-point Obama victory in NC means Clinton needs a 6-point victory in IN just to stay even.
