PA had no impact, or so Rasmussen says --
http://www.rasmussenreports.com/public_c ontent/politics/election_20082/2008_pres idential_election/daily_presidential_tra cking_poll In the race for the Democratic Presidential Nomination, it's Obama 49%, Clinton 42%. Those numbers are unchanged from the night before and, so far, there is absolutely no indication that Clinton's victory in Pennsylvania has changed the overall dynamic of the race. These results are based upon a four-day rolling average and include two full nights of polling following the Pennsylvania Primary.
The numbers haven't changed because Clinton's win was expected. She will have to overtake and beat him somewhere where he is expected to win, as she did in NH.
Hillary's gonna have to fight hard to win NC in order to change the game.
More from Rasmussen
"These results and other data suggest that there is no "momentum" in this Primary Season. Typically, momentum results as voters learn more about a candidate who is doing well. This cycle, Hillary Clinton began the campaign as one of the best known people in the world. Democrats uneasy with her quickly settled on Obama as the chief challenger who has now become the frontrunner."
