No, the headline is not missing any zeroes... New Hampshire lawmakers really do get paid just 100 dollars a year, plus mileage.
The New Hampshire Liberty Alliance is trying to keep it that way by opposing a proposed constitutional amendment that would open a path to increasing this amount. This amendment would, in their view, threaten the state's tradition of a what amounts to an all-volunteer legislature.
If you live in state you can contact the committee that will vote on this, at HouseLegislativeAdministration@leg.state.nh.us
I'm projecting that February 4th would be roughly the deadline for contacting them before they decide.
Does your state have an organization that tracks and fights nearly every anti-liberty (not just anti-Republican) move by your legislature? If not, move to NH where we do!
