That's the real issue, and it's weird that so few seem to realize it. Sure, they skew Republican because stay-at-home moms tend to skew that way too. As you said though, it all predates both presidents. It was the crunchy parents before COVID, and often times still is.

This is true, but leading up to the vaccine, he embraced every stupid conspiracy, related to COVID and before. Remember the bleach and sunshine press conference? A better leader who actually tried to understand the science at a basic level when they have their choice of incredible experts would have been better at communicating to the public from the beginning. He let the horse out of the barn, and that's famously hard to undo.
