Progressives in Maine’s largest city are rushing to put an aggressive economic agenda on the November ballot, including an $18 minimum wage and new restrictions on housing and cruise ships.The campaign to put four questions on the Portland ballot comes from the Democratic Socialists of America, which led another progressive slate of referendum questions in 2020 that enshrined a minimum wage that will rise to $15 by 2024, plus rent control and a “Green New Deal” that mandated affordable units and heightened environmental standards on certain new buildings. All of those questions were opposed by business interests led by the Portland Regional Chamber of Commerce against progressive figures in the city.
