A new SurveyUSA poll in Pennsylvania shows Sen. Hillary Clinton's lead over Sen. Barack Obama shrinking over the last few weeks.
Clinton leads 53% to 41%. However, compared to an identical poll three weeks ago, Clinton is down two points and Obama is up five, with Clinton's previous 19-point lead cut to 12.
Key finding: "The movement in support came almost entirely from men, according to the survey results. Clinton had led by five points but now trails by seven -- a 12-point swing to Obama."
