Presidential polls in Pennsylvania suggest that Barack Obama is gaining ground on Hillary Rodham Clinton by drawing more support from men and younger voters.
According to a Quinnipiac University poll released today, Clinton is ahead in the state 50 percent to 41 percent. However, Clinton's lead has steadily eroded from 16 points in mid-February and 12 points in mid-March in the same survey.
Clinton trails Obama in the national popular vote and among delegates to the party's August convention. But she is expected to do well on April 22nd because Pennsylvania has large numbers of voters who typically support her, including older people, whites, and those without a college education.
The Quinnipiac poll was conducted from March 24th through March 31st. It involved telephone interviews with 1,549 likely Democratic voters.
The margin of error was plus or minus 2.5 percentage points.
