I’m not sure what to make of all the increases/gains the Rs have had in registrations. Common sense would tell you that’s good for Trump and bad for Biden. But there is something of a political realignment going on. There are people who have historically been conservative who are disgusted by Trump, and will vote against him, irrespective of how they’re registered. Likewise, there are people disgusted by what they see on the left these days, and will vote against it. Over the years we’ve heard countless stories of people who were faithful Democrats all their lives - until the chaos of the 1960s. “I didn’t leave the Democrat Party, it left me”. I suspect years from now we’ll be hearing a bunch of that, from both sides this time. Anyway, everything is so volatile, I don’t know if it’s as simple as “increase in registrations in R counties = more R votes.”
