As Monday is Presidents Day and we're now into the preceding weekend, we'd like to hear about your favorite movie or movies involving Presidents or politics!  Whether it's a political comedy like Dave, or a more serious biopic like JFK, we want to know.  Maybe a recent one like W. or Charlie Wilson's War, or even a cheesy action like Independence Day.  I've listed a few to get us started, what do you think?
