I did not recognize this Rep by name. He represents parts of Brookline. OMG that is a bastion of liberalism and it also has a very affluent electorate. There are also quite a few Jewish voters there. Brookline is a very big Jewish area in Massachusetts. This could be very big if it starts a trend. Do you have a link to the announcement?
