marshall7798 may be right - The Larouche people are all over the place in Massachusetts, and they will set up shop anyplace they can find an audience.
It seems there are many (at least around here) who dislike Obama, but won't vote for Romney either. But that's okay. The LaRouche people are almost exclusively college kids who probably voted Obama the first time around, and are now unemployed, and living at home.
One vote less for The Great and Powerful O is one less vote.
