Clinton holds advantages over Sanders among men, 50 percent to 41 percent, and women, 61 percent to 32 percent, as well as among older voters.

Pennsylvania is the biggest delegate prize of the five state voting Tuesday, a week after Clinton expanded her lead with a decisive win in New York.

Like New York, it is also a closed primary in which only registered Democrats may vote.

“After her win in New York this week, these numbers in nearby Pennsylvania suggest that the entire northeast is looking pretty good for the Clinton campaign,” Monmouth University polling director Patrick Murray said in a statement accompanying the poll.

In Connecticut, another state voting Tuesday, Clinton leads Sanders by 9 points, according to a Quinnipiac University poll released earlier Wednesday.

Sanders kept up his attacks on Clinton's ties to Wall Street during a rally in Pennsylvania on Tuesday afternoon. Clinton's campaign has called for a more civil tone going forward.

Eighty-one percent said they would back her, compared to 11 percent who said they'd back Trump.

The Monmouth poll of 302 likely Democratic primary voters in Pennsylvania was conducted April 17-19 via landlines and cellphones with a margin of error of 5.6 points.
