George Will might be terrible at analysis and predictions, but he knows DC inside and out, and I trust him a lot more on issues like this than O'Reilly. That being said, I imagine the Fox News crowd probably watched that and thought O'Reilly won, so I voted for a tie overall.
Although what they're arguing over is O'Reilly's claim that Reagan was brain-damaged after the 1981 assassination attempt to the point of being incapable to continue as president. So that probably gives Will a pretty big boost with the Fox News crowd.
