With presidential voting underway in Massachusetts, it remains an open question what Republican Gov. Charlie Baker will do when he pulls a ballot later this evening. The only thing he's said for sure is that he won't be voting for President Donald Trump, whose supporters plan to gather in Quincy.

While many statewide officials, including Secretary of State William Galvin, and U.S. Sens. Elizabeth Warren and Ed Markey voted early this morning, Baker is not expected to arrive at the polling location across the street from his Swampscott home until tonight. Aides to the governor say he is expected to vote after work, probably close to 7 p.m.

Baker has said that he doesn't want to get involved in presidential politics, though he has said that like in 2016 he won't be voting for Trump. Also on the Republican presidential primary ballot in Massachusetts is former Gov. William Weld, former Illinois Congressman Joe Walsh, who suspended his campaign last month, and Roque de la Fuente.

Baker will also have a choice on his ballot between incumbent Republican State Committee member and former Salem State University trustee Richaerd Zykofsky and challenger Richard Wood. Amy Carnevale is the only woman running for the other GOP State Committee seat in the Third Essex District.

Baker's name is also on the ballot. He is one of 20 people, including former Republican nominee for secretary of state Anthony Amore, running for 35 seats on the Swampscott Republican Town Committee.

The Massachusetts Republican Party, the president's Massachusetts campaign chairman Sheriff Tom Hodgson and Republican National Committeeman Ron Kaufman will be hosting a Super Tuesday party at the Victory Point Restaurant and Bar in Marina Bay, Quincy starting at 7:30 p.m. A Baker political aide did not respond when asked if the goveror, the state's top elected Republican, planned to meet up with his party mates in Quincy.
