If the Democratic Primary were held in Pennsylvania Tuesday, Hillary Clinton would beat Obama by 18 percentage points, according to the results of a SurveyUSA poll conducted exclusively for NBC 10 and three other TV stations across the Keystone State.
(snip)
Last week, Obama moved within 12 percentage points of Clinton, but men who flirted with the notion of voting for Obama at the end of March appear to be moving their support back to Clinton...Obama also lost ground among voters between 35 and 49, down 18 points, while Clinton continued to lead among voters 50 and older.
In the Southeast section of the state, which includes Philadelphia and makes up 42 percent of likely Democratic voters, Clinton had a good week, polling above 50 percent for the first time...In the southwestern part of the state, which includes Pittsburgh, Clinton jumped 25 points ahead of Obama. However, the Johnstown area continued to show consistent movement toward Obama, the survey concluded.
Obama also lost ground among moderates and liberals and conservatives. Clinton only fell among conservatives.
