As he fights his way through a tough Senate re-election campaign, Sen. Scott Brown (R-Mass.) is making a lifestyle change. In a Friday interview on Boston's WTKK-FM radio, the incumbent said he is giving up booze until November's Election Night. Brown noted that he has not had any type of alcohol since January 1, referring to the adjustment as "one of those New Year's things" that he did "on a stupid bet." Brown's battle with Democratic challenger Elizabeth Warren had its highlights this week, with taxes at the forefront of the conversation.
