What matters is perception and public messaging and that is currently one of a centrist president incapable of reigning in a foreign ally or continually calling out House Republicans for their shenanigans that put American lives at risk at home and abroad.
Conservatives have constant control of the conversation because they have zero qualms publicly stating how their political adversaries stand in their way. But instead it looks like Democrats trying to win Republicans support by adopting republican policies instead of bullying them into accepting the plan of the majority party of the upper legislature and presidency.
Oh yeah, if he started talking like half of his most rabid supporters do online then he'd be way more popular.
If people could quote President Biden's personal attacks on white supremacists, book bans, etc then they'd get a lot farther with the politically disengaged.
Imagine if you had Biden (or his social media team) out here on the daily constantly mocking GOP culture war shit as inherently un-American and out of touch with normal people?
