Massachusetts, and presumably Oregon... are doing something funky behind the scenes to choreograph this one-party putsch.
Has something to do with some or all (and more) of: Agenda-21, building codes, encouraging the “Big Sort”, state campaign finance laws, “affordable” housing, sanctuary cities/states, ...
Between environmental regulations and land use/zoning restrictions, Oregon is perfecting a form of utopia called the "no-growth economy".
In time, it will become a Luddite colony trapped in amber.
