There’s more evidence of how the race in Pennsylvania is tightening between Hillary Clinton and Barack Obama, despite one out-there-all-alone poll released this week by SurveyUSA that showed Hillary Clinton ahead by double digits.
Public Policy Polling says a survey conducted April 7-8 shows Clinton ahead 46 percent to 43 percent, with the margin of error at 2.9 percent. Last week, she was 2 points behind Obama and, in mid-March, Clinton had led 56 percent to 30 percent in this poll.
