First lady Michelle Obama is making a political swing through New England on behalf of Democrats running for governor in Massachusetts and Maine.

Obama energized a crowd at the Strand Theatre in Boston's Dorchester neighborhood during a rally for state Attorney General Martha Coakley's gubernatorial bid, warning that "races like this can be won or lost by a few thousand or even a few hundred votes."

Obama said the midterm elections are so important that she and her husband are both on the road even though it's their 22nd wedding anniversary.

Polling indicates Coakley is locked in a tight race with Republican Charlie Baker.

The first lady later is scheduled to attend a rally at the University of Maine in Orono for Democratic congressman Mike Michaud, who is challenging Republican Gov. Paul LePage.
