If that were true, it'd be great. But which is the party that supports municipal broadband for all residents as a public utility? California has a Democratic governor, Democratic legislature, and in the most populous areas Democratic local government, and yet no municipal broadband.
There's a map here of which state legislatures have passed restrictions on municipal broadband, and it seems pretty idiosyncratic relative to blue/red politics: https://broadbandnow.com/report/municipal-broadband-roadbloc... E.g. WV, OH, IN, IL, KY, GA, NM, VT are friendly to it, while WA, OR, TX, CO, AL, PA, FL, MA are unfriendly.
