You’re seeing what I would call the “red mirage” after this election. The extreme shift of the GOP after the last presidential cycle has taken the party very far out of step with the electorate in much of the country. Remember, Trump did not win the popular vote in either election. As a Democrat, I see this as good news in the short run. Part of the issue is that the primary process is inherently very flawed- it produces bad candidates on both sides that appeal to the most ideologically extreme part of the party that bother to vote in primaries. I think the RCV that Maine and Alaska is an antidote to this and allows for more broadly appealing candidates like Collins and Murkowksi, even though that may be bad if you’re a democrat.
