Nathan 'Nate' Libby is an American politician from Maine. Libby is the Senate Majority Leader and represents Lewiston, Maine's second largest city, in the Maine Senate.
In 2013, Libby co-wrote comprehensive tax reform legislation that would lower the state income tax, broaden the sales tax and expand the homestead property tax exemption to $50,000, but the measure failed to pass the Legislature. Libby was the primary sponsor of legislation to restore consumer rate review in the individual- and small-group health insurance markets, a measure enacted by the Legislature but vetoed by Governor Paul LePage.
In 2016, Libby worked with Maine Senator Eric Brakey to pass legislation that limits what welfare recipients can spend their benefits on. Libby's bill banned the use of welfare cash on tobacco, liquor, gambling materials, lottery tickets, bail, firearms, vacations, adult entertainment and tattoos.
