People aren't "Republicans" or "Democrats" or whatever. They're people. Of course "Republican support" collapses in communities once you start asking people what they want.
You would wish but it's way too prevalent to call oneself "Republican" or "Democrat" and promise lifetime loyalty. Take almost anything they are mad about when the "other" side does it and ask how they'd feel if "their" side did it.
Both my parents are/were this way for Republicans. They don't care about the sexual assaults, the destruction of the government, or the billions of dollars of corrupt money heading to the president and his cabinet. Or worse, he outright calls me a liar when I inform him of the facts.
He can say billionaires are unethical ipso facto, that the poor shouldn't die from lack of healthcare, and that corruption is bad. But then say he has no choice but to vote Republican because "Democrats are worse" and "they want to turn boys into girls.". He thinks Fox News is too liberal.
They certainly exist, and in great numbers, if there aren't 75 Democratic senators and 300+ Democratic House reps by 2028.
The comment makes perfect sense, especially given the current political climate of the US and what Republicans are clearly indicating they want... Not sure what you are on about.
Republicans have campaigned on discrimination, bigotry, sexism, establishing a dictatorship and punishing dissenters for the last 10~ years minimum - definitely longer than that considering the last century. If someone votes for a candidate campaigning on those things the voter is complicit in those things gaining strength. Stop writing off that behavior and hold them accountable for who they are clearly signaling they are.
