Scott Brown having won a special election in Massachusetts showed that it's not impossible for a Republican to win a Senate seat in Mass. even if it is unlikely.

Since the Boston bombings the Senate race has understandably taken a back seat in the local media. Oddly enough Gabriel Gomez was actually near the finish line of the marathon when the bombs went off. He talks about this, as well as his background with Greta Van Sustren:
