Quinnipiac polls are leftist garbage.
If he’s “up” in Wisconsin; PA and MI are uncontested.
The state vote margins stay fairly stable *in relation to each other*; it’s just a matter of where the center of the vote falls on the D to R spectrum.
For example; Ohio is nearly always +5 to +7 R compared to Pennsylvania.
So; Ohio +9R = PA +1R for example. Ohio +3R = PA +5D.
