Perhaps separate statehoods would be the best thing in all of these instances. It wouldn't be a case of creating additional blue states - the states in question are already blue. Instead, it would create new (albeit smaller) Republican states with two new Republican Senators and retaining the conservative upstate Congressional districts. The Senate and Congressional count from the liberal metro areas would remain unchanged if they became independent, in contrast.
I say that it's a win-win situation for us, so by all means let the Upstates start their divorces from the Metro areas.
