A new poll from Suffolk University suggests that we could have another close special election for a Senate seat in Massachusetts on our hands.

Two weeks before the election for the seat formerly held by Secretary of State John Kerry, Democratic Rep. Ed Markey leads Republican Gabriel Gomez among likely voters by seven points, 48 to 41 percent.

That's a significant shift from a month ago, when Suffolk had Markey leading Gomez 50 to 35 percent.

“Ed Markey continues to lead, but the margin has dwindled,” said pollster David Paleologos. A likely cause, he says, are concerns about Obama administration scandals.

There has been little independent polling in this race; a recent Republican survey had Gomez and Markey tied.
