There has to be at least one out there (or will be after november)
I would say probably just a 18 year old voter in 2012 who had liberal parents and they did what their parents did by default, then in 16 fell for the idea of trump being this anti Christ, but moved out by 2020 and moved to a more conservative environment and adapted their views naturally to fit that and actually felt he was s decent president
This voter doesn't exist. Only like 8% of voters under 30 identify Republican, problem is they don't hardly vote.
I would say the actual voter you are thinking of is hippy dippies who smoke weed and watch too much Youtube and have now been duped into the Qanon conspiracy, AKA my adult sister. Except she voted for Jill Stein instead of Hillary. Lately she's been dropping nut job lines like "maybe Covid is a Democratic hoax."
