There's been lots of discussion about "brokered" or "open" conventions regarding the race for the Republican Presidential nomination. It's been a long time since the country saw one of these, and few are familiar with the political process as to what happens if no candidate has a majority of votes on the first ballot.
I remembered a great movie about an open convention and it would be good for you guys to watch it and learn how the process works. It's called "The Best Man" starring Henry Fonda and Cliff Robertson. They're two front runners for the nomination who don't quite have enough delegates. It's a great look at those backroom deals in the smoke-filled rooms, and how the process can eventually play out.
It was released in 1964 (I can hear you kids saying, "Ewwwwww.... it's old") but it's a terrific movie. You can probably get it from Blockbuster or Netflix or buy it from Amazon if you're so inclined. By the way, there are about five movies out there with the same title... make sure you get this one or you'll end up watching a rom-com.
