Not even getting into personal politics, Clinton has very little chance to get the party's nomination. It's just simple math. At the current delegate count, she needs higher than 60% of the vote in every remaining state just to barely nudge out Obama. PA was the last big state where she had a substantial lead going into the election (started at 20 points). Still, she only managed a 10 point victory, which was much lower than what she needed. It's enough to keep her going, but that's about it. The super delegates could swing the count in her favor. However, that would seriously damage the party's credibility since Obama is currently favored by the popular vote.
The Democratic primary is nuts though. I worked at my precincts polling station (about 14 hours 
) and the turnout for democrats was gigantic. PA is a left leaning state, but they outnumbered the republicans by about 4:1.
On a side note, if you ever want to feel good about who you are, work an election day at a polling station. There are some...... "colorful" folks out there.
