Most of them were already Republicans and will stay that way. The Obama-Trump voters will split three ways, with a third going Republican, a third going back to the Democrats (if they hadn't already in 2018 and or 2020), and a third not voting at all.
Do you think that the MAGA crowd (I'm talking about the people that ransacked the capitol) were Obama-Trump voters?
I don't see it, but I suppose its possible.
My God January 3rd when I wrote that post feels like a whole other era now. That said, I think if they were, they were a very small minority in that group.
