In my anecdotal experience, vaccine hesitancy, or whatever you call it, cannot be attributed to a party allegiance in the US. There are as many if not more liberal vaccine refusers as there are conservative ones
No, there aren't, unless you torture the definitions to the point of uselessness, or unless your personal experience means that you personally know 50 liberals and 5 conservatives (and 6 unvaccinated people, split evenly between the two). [1]
Or, if you have to use your eyes to believe it, look at any vaccination rate map [2], and contrast it to how those states vote.

Why must there be a single attributable factor? It seems likely that there are multiple. Party allegiance certainly appears to be one of these from numerous polls and analyses [1]. Poverty and insurance status is likely another [2].
