Pennsylvania Primary Update

With just about 3 weeks left until the Pennsylvania Primary, Barack Obama is closing the gap between himself and Hillary Clinton. A recent poll by Rasmussen shows:
Who do you plan on voting for in the Democratic Primary?
Clinton: 47%
Obama: 42%
Not sure: 11%
The survey was conducted among 730 randomly selected likely Democratic primary voters. Its margin of error was +-3%.
A week ago, Barack Obama was down by ten points, and on 3/13 he was down by 13 points. Clearly Obama is gaining ground and has lived through the Pastor Wright controversy. While he probably won’t win in Pennsylvania, if he can keep the vote close he’ll deal a crushing blow to the Clinton campaign. They need a big delegate boost and huge popular vote gains to continue taking their argument to the superdelegates that she should be the nominee.
As a side note, Obama is leading 54% to Clinton’s 36% in North Carolina. With a close Pennsylvania vote, this will likely erase any gains by Hillary in Pennsylvania.
