Just watch it.
This sort of thing just doesn't happen anymore in America today, where politicians stand face to face and debate each other on camera. No scripts, no talking points, just argument and reason. The founding fathers knew this was central to our democracy, and so did many of the founders of the modern conservative movement. People like William Buckley, and Ayn Rand. These are people who didn't seem to believe that you should build a political base by appealing to the lowest common denominator in American society. The main protagonist in Rand's "Atlas Shrugged" is John Galt, a man who has infinitely more in common with Barack Obama than he does with populists like Sarah Palin.
I hope this sort of thing continues to happen. My speculation is that it won't. I imagine the Republicans will realize that their political fortunes are better served by issuing cheap talking points than by challenging a demonstrably more adept mind than apparently the sum of their own.

After watching the video of Obama talking with House Republicans, view this one minute clip from Fox News and ask yourself whether they are doing their job, which is to keep the American people informed.
