Democratic U.S. Senator-elect Troy Jackson is already drawing attention in Washington over who he’ll back for Senate Majority Leader.

Jackson is one of at least eight newly elected Senators who have flipped the chamber into Democratic control, and Jackson has said he will not back current Minority Leader Chuck Schumer.

The Bangor Daily News reports a union leader close to Jackson has said there’s a “98% chance” Jackson will back Senator Chris Van Hollen of Maryland.

Meanwhile, Jackson has not publicly stated who he’s backing, and told WMTW he has not me Van Hollen and will not vote for him just because he’s the alternative.

Van Hollen has emerged as the leading opponent to Schumer.

Jackson reportedly met with a leading member of the International Association of Machinists and Aerospace Workers and agreed the Senate needed new leadership.

The Machinists union represents shipbuilders at Bath Iron Works, and endorsed Jackson in July.

Jackson’s possible support of Van Hollen would put him at odds with Maine Independent Senator Angus King, who announced Friday that he’s is backing Schumer to lead the chamber. King, like fellow Independent Senator Bernie Sanders of Vermont, caucuses with Democrats.
