The final Republican debate of the year wrapped up in Las Vegas Tuesday night. Meanwhile, a new survey by the Pew Research Center found that nearly two-thirds (65 percent) of those who watched previous presidential debates in this election cycle say they have been helpful in learning about the candidates.
