Pennsylvania voted today in its democratic primary, which may finally put an end to the long-running contest between Hillary Clinton and Barack Obama. Pennsylvania is the largest state remaining, and Clinton needs to win big if she is to convince superdelegates to continue to back her rather than her rival. If she doesn't, then the pressure to fold will be immense. Of course, they've said that about every previous primary as well, so it can probably be taken with a grain of salt.
The polls closed less than an hour ago, and results are begining to trickle in. From the exit polls, it looks as if Clinton has done well enough to stick around - which means people in North Carolina, Kentucky and Oregon might get to vote after all.
