It likely skews data in conservative states, but likely not by much. At least in 2020, mail-in voting was presented as the greatest boogeyman to ever threaten the GOP that week. That pushed conservative voters to vote in person in conservative states and make a big show about how much more reliable and traceable it was. Democrats already trusted the mail-in option. Conservatives in my blue area were not as polarized by this threat, in my observation, and still used the mail-in option. I imagine they knew they’d be overrun in the electoral vote so it didn’t matter if the popular vote was accurate or not.

This time around, I’m out of the Reddit loop and I’m not subjected to Fox News every day, so I’m not as in touch with the vibe.
