LANCASTER, Pa. (CBS) - A new poll shows that support for gay marriage in Pennsylvania has reached the 50 percent mark.

The new Franklin and Marshall College poll shows 50 percent of Pennsylvania residents would support a Constitutional amendment to legalize gay marriage. That’s a gain of eight points since an F&M Poll two years ago.

In the current survey, 42 percent “oppose” and eight percent answered “don’t know.”

But poll director Terry Madonna says more people with strong opinions on the subject are against it:

“Thirty-three percent say they ‘strongly’ favor it, but 37 percent ‘strongly’ oppose.”

Among the poll’s other findings: 53 percent of respondents think the state is headed in the wrong direction, with 47 percent citing unemployment as the biggest problem in Pennsylvania.

Only 34 percent think President Obama is doing an “excellent” or “good” job; even fewer say so about Governor Tom Corbett and the state’s two US senators, Pat Toomey and Bob Casey.
