Democrat Ed Markey and Republican Gabriel Gomez were out trying to get some last-minute votes Tuesday. Gomez stopped by Mr. Bartley’s in Harvard Square, and ordered the Gomez Burger, naturally, topped with American cheese, grilled onions, and jalapenos. Meanwhile, Ed Markey did some glad-handing at Kelly’s Roast Beef in Medford, then enjoyed some chicken fingers with mayor Michael McGlynn.
