The fact you even look at politics puts you in like, the top 20% of the US population.
I would wager the majority of people that do vote, just look for an R or D next to a name and check the box for their team and move on.
There were about 160 million people who voted in 2020, an unprecedented amount of engagement from the voting populace, and still not half of Americans voting.
People don’t really care. Do they have a job? Are their basic needs met? If yes, vote incumbent, if no, vote competition. I expect to see tweets in November asking where Biden went and who is Kamala.
