It’s Sen. Mark Begich’s 52 birthday on Monday, and the National Republican Senatorial Committee was sweet enough to send him a cake to his D.C. office, onto which was written, “Happy Birthday to the Senator that votes with Obama 97 percent of the time.” Any good? I asked his office. Nah. They said that much like the NRSC, it was “just plain vanilla with artificially sweetened facts.”
