In OR, even with D supermajorities, we needed a few votes of rural market-fundamentalist Rs to get the bill past Ds from rich exclusionary burbs.
If VA's duplex bill passes, I think that door closes.
In case you haven't noticed, there is a group of smart Rs racing to align their party with this (correct) policy position before Ds embrace it.
1) D cities would double down on "if anyone anywhere is making money from physical change, then that change is bad" (ignoring the rivers of gold exclusionary zoning sends into landlord pockets)
(this is already where mainstream Rs gravitate in all housing debates)
But if I have to choose either D or R territory to be politically pro-housing, gonna go with the central cities & inner burbs.
But the idea shapes the party, too.
