It's poll data produced by Franklin & Marshall College.
Here's the money shot:
More than half (57%) of registered voters in the state support an impeachment inquiry, with nearly half (47%) expressing “strong support” for the inquiry. Supporters of the inquiry believe the President has broken the law (36%), has participated in a corrupt or criminal act, or that the inquiry is needed to uphold the Constitution (14%). One in seven (16%) supports the inquiry because they want to discover the truth. On the other hand, nearly two in five (37%) registered voters “strongly opposes” the inquiry. These opponents believe the inquiry is partisan politics (28%), fake news or anti-Trump propaganda (17%), a waste of resources (12%), or that the President did nothing wrong. Few Republicans (21%) or conservatives (18%) support impeachment, while almost all Democrats (84%) and liberals (97%) do. At the moment, majorities of independents (61%) and moderates (67%) support impeachment.The next paragraph is interesting in itself:
Notably, only one in five (21%) registered voters in the state believes it is acceptable for a president to ask a foreign leader to investigate a political opponent, although Republicans and conservatives are most likely to believe it is acceptable.Elsewhere in the report, we learn that 71% think it's unacceptable for a president to ask such a thing.
There's also another question that asks:
What, if anything, do you think should be done about the president requesting this political help from a foreign leader?52% said impeachment.
Granted this is poll data and poll numbers always change but this is a picture of what Pennsylvanians think in late October, 2019.
