Lexington resident Jill Stein, an environmental-health advocate and recent Green-Rainbow Party candidate for Massachusetts governor, will officially kick off her campaign for the presidency at the State House Monday afternoon.

As Stein occupies Boston, part of her message could resonate with some others doing the same.  According to her website, Stein seeks to reverse the concentration of power and wealth controlled by the top 1 percent and supports the adoption of a single payer, improved Medicare for All program.

"A key focus on Stein's campaign will be a Green New Deal to end unemployment in America and jump start a real recovery from the Bush/Obama recession," according to a media advisory from the campaign. "The Green New Deal will provide public jobs to the 16% of Americans who need one, including green jobs that will transition America to a secure, green economy for the 21st Century."

If Stein's name looks familiar to Lexington voters, it's for good reason. She's been elected twice as a Town Meeting member. And twice she's run as a Green-Rainbow Party candidate -- for State Representative in 2004 and for Secretary of State in 2006. Stein has also run for Governor twice, including the most recent race and in 2002, when she faced Mitt Romney, who is seeking the Republican nomination in 2012.

Stein will seek the Presidential nomination of the Green Party and expects to qualify for the ballot in at least 40 states, according to her website, which said she also expects to qualify for Presidential primary matching funds.
