I think the bolded is generally true right now across the U.S. – but for the sake of precision, let’s note that this article is specific to Michigan voters. They’re a swing state, of course, so what’s happening in Michigan is important to watch.
An aside: I believe that the “not looking forward to Biden-Trump II” factor has been a BIG confounder in head-to-head polls attempting to get an over-the-horizon view at November’s general election. Some respondents are doubtlessly giving “protest answers”, most especially those tepid on Biden (saying they’re ‘undecided’ most likely). I’m curious to see what the same polls (incl. swing-state specific polls) look like after the conventions, when both candidates are locked in.
