New Mexico has been on a progressive roll lately
Then again, state legislators in New Mexico have no salary and work for free if I recall correctly
That's not the sort of thing that would make them more progressive.
Anyone who'd be willing to volunteer to be a state legislator probably loves being involved in politics for the betterment of society. I feel like you'd end up with more honest people when money isn't a factor
Anyone who has enough money to "volunteer to be a state legislator" is not going to be naturally inclined to support progressive policies. And if they don't have enough money, but "volunteer" anyway, they're probably going to be looking for new ways to supplement their income...
