Ideological Split: There seems to be a trend in the reporting: there actually isn’t much of a partisan split in attitudes about the virus itself. One recent poll found support for mask mandates was at 72% overall. 86% of Democrats in the poll supported them, 58% of Republicans.
But anecdotally, the actual point of disagreement I see among Trump-aligned ideologues has changed. They no longer deny that the virus exists or that it can cause major health problems or that it has a high fatality rate compared to the flu. Most frequently the claim is that there is a simple cure to the virus but that doctors who know about it are being censored through some kind of conspiracy.
