LOWELL, Mass. -- During Monday night's Senate debate here, incumbent Republican Scott Brown was asked by NBC's David Gregory to name his model Supreme Court justice. The name that came to his mind may cost him with the state's Democratic voters: Antonin Scalia.

"Let me see here, that's a great question. I think Justice Scalia is a very good judge," Brown said. GOP members of the crowd roared with approval as those on the other side booed just as loudly. Brown's Democratic opponent, Elizabeth Warren, appeared just as happy to hear the answer.
