This. In general the big argument all along has basically been “The government can’t tell me what to do!” or “These government policies are hurting my small business”.
There’s a large chunk of people out there who still have a more or less toddler-and-vegetables mentality when it comes to someone “telling them what they have to do”, and will resist it tooth and nail, even when it’s sensible, logical and polite to do so. To them, their right to self-determination trumps anything else, including science, logic, good sense, or social norms.
The kicker from what I see is that they’re kind of ill-equipped to exercise this self-determination; they only dig their heels in and go full 3-year-old when “trusted” sources tell them they’re being told what to do. It’s not like they’re listening to the news, seeing the pandemic coverage, critically thinking about it, and making a conscious decision to NOT wear masks or get vaccinated. It’s totally a matter of them watching their news, having some dickhead like Tucker Carlson throw shade at vaccinations and masks for being government overreach and Democrat-related, and their brains shut off, and they refuse like a toddler refuses to eat vegetables. There’s no logic or common sense there- they’ve made up their minds, and NOTHING is going to change it.
I have zero doubt that if in early 2020, the Republican/conservative side of things had taken a personal responsibility tack- sort of a “We won’t tell you what to do, but we’re going to remind you that the responsible person’s behavior is to wear masks and get vaccinated” approach, combined with some shade thrown at minorities for being “irresponsible” for not doing so, we’d have super-high mask compliance and vaccination rates among that crowd.
But that didn’t happen; instead, the cynical bastards in charge made it into a matter of personal liberty, and they dug their heels in. And in a further “benefit” for those bastards, now it’s an identity thing- not wearing a mask or getting vaccinated has been a way to trumpet your opinions and stance, and also reinforces one’s identity as a conservative and Republican.
So with this reinforcement, they’ve set themselves apart, and primed themselves to be targets for whatever Republican candidates come along. That’s how the GOP stands to gain by not intervening- they basically let their voters self-segregate and pull themselves further right.
