President Trump is sinking further underwater in the critical swing state of Pennsylvania, according to one of the worst polls for him in the state so far.

A Monmouth University poll of Pennsylvania voters conducted July 9-13 found that 53% supported Biden and 40% supported Trump, a 13-point lead. When accounting for likely voters rather than all registered voters, a more accurate measure of what the outcome of the election would be if it were held today, Biden’s lead over Trump ranges from 7 points, with 51% choosing Biden and 44% choosing Trump, in a low-turnout scenario to a 10-point lead, with 52% choosing Biden and 42% for Trump, in a high-turnout model.
