Pennsylvania Primary Day

Today is the long awaited Pennsylvania Primary. The latest polls show that Obama is unlikely to win the popular vote given Clinton's family connections and political machine, but he could still be seen as victorious. If Obama can somehow come within 10% of the heavily favoured Hillary Clinton, it would be seen as a huge accomplishment. Don't forget, Clinton was once up by more than 20%! If she wins by more than 10 then her (slim) reason for continuing remains. It's also important to know that for Clinton to actually make up significant ground in the delegate race she would need to win by a very big margin , even more than by the originally forecasted 20% margin.
