PORTLAND, Maine (AP) Republican Sen. Susan Collins isn’t talking about how she voted in Maine’s uncontested presidential primary.

President Donald Trump, also a Republican, is the only candidate on the state’s primary ballot. Collins declined to vote for Trump for president in 2016, when she wrote in former Republican House Speaker Paul Ryan.

Collins says in an interview with WCSH-TV that she has already voted by absentee in the Republican primary this year, but she declined to disclose if she voted for Trump this time. Maine goes to the polls on Super Tuesday.
