Obama wins Pennsylvania. Clinton concedes. Democrats unite!

A campaign tactic that Obama can employ is to let Pennsylvanians realize the power they have to unite the party and thus enable it to win the White House. Hillary, pundits and the DNC all have said or hinted that if Hillary loses Pennsylvania (grr, it's so hard to spell) she will realize that her campaign has ended and there's just no realistic way for her to win the primary. She will thus gracefully exit, giving a concession speech that will unite the party and repair her legacy.

So Pennsylvanians, and campaigners in Pennsylvania, do the right thing! Unite the party! It's in your power! Yes you can! make this dream come true: "Obama wins Pennsylvania. Clinton concedes. Democrats unite!"

Please discuss.
