A surging Donald Trump has cut Hillary Clinton’s lead in the crucial state of Pennsylvania to just 4 points, according to a new poll from Monmouth University.

The survey, which has a 4.9 percent margin of error, showed Clinton clinging to a 48 percent to 44 percent lead among likely voters in Pennsylvania. Clinton held a 10 point lead (50 percent to 40 percent) in the Keystone State in last month’s poll.
