Democratic U.S. Sen. Martin Heinrich has been re-elected in a three-way race against a Republican political newcomer and a Libertarian former governor.
The 47-year-old engineer and former Congressman won a second term, finishing ahead of construction contractor Mick Rich and former New Mexico Gov. Gary Johnson. Heinrich's victory further solidifies Democratic control over the state's Senate delegation.
Heinrich cast himself as a vigorous adversary of President Donald Trump's policies in the Senate, and campaigned on promises to defend federal health care and retirement programs.
Heinrich recently became an advocate for decriminalizing marijuana, co-opting one of Johnson's signature Libertarian issues against government interference. He derided Johnson's proposals to slash federal spending on Medicare, Medicaid and the military.
Rich ran on his reputation as a businessman while embracing Trump and voicing anti-abortion sentiments.
