This polls education sample is off, it has 52% with a bachelor degree or higher, including 24% with a post-grad degree, those numbers are way to high, as of the 2018 ACS, 34% of adults in PA had a bachelor degree or higher, among RV's it would be somewhat higher, and more educated voters turn out at a somewhat higher rate, but the share in this poll should be in the mid 30's, the 2018 exit polls had 39% of voters in PA having a bachelor's degree or higher.
Um, no. There's no way that this poll is somehow skewed towards Biden looking at those #s. If anything, it's the other way around, since the numbers for Dems all around are much lower than elsewhere (Wolf's +7 approval tells us this)
I'm not saying anything about whether it is skewed or not, I was just pointing out the education level in the poll is to high.
