With a matter of 100 delegates between them and many super-delegates still in need of convincing, Hillary Clinton has launched her push to win Pennsylvania. One thing of benefit to her cause was a gig by Elton John that raised $2.5 million, but what is more important; his endorsement of the cash? Clearly there is a degree of synergy between his appearance and her use of the I'm still standing line. But perhaps of more help has been a gaffe, well perhaps an ill-judged line, from Obama. His statement about the disillusioned working class has been spun by opponents to make him appear patronising. His observations was: "You go into these small towns in Pennsylvania and, like a lot of small towns in the Midwest, the jobs have been gone now for 25 years and nothing's replaced them. And it's not surprising, then, they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations". Interestingly attacks have come from both Clinton and McCain, which suggests that not only does Clinton see him as the main rival but so does McCain. The big questions is will either his comments or Elton's appearance have an impact on the contest? With 10days still to go to the Pennsylvania primary he has time to recoup as does Clinton to drive public opinion against him; so who will the voter believe. If the voters in Pennsylvania did not "need a president who looks down on them", as Hillary claims, and Obama becomes linked with looking down on them as opposed to being one of them it could be quite damaging.
