Ezra Klein wrote a good post on his blog about how differently our Congress functions these days than it used to, specifically in regards to the filibuster. He included this helpful chart to demonstrate.
As you can see, things aren't quite the same as they used to be. No President or single member of Congress we elect, no matter how great they are, is going to be able to overcome the problems inherent in the way our government works. We need a different system and I don't mean throwing out everything we have and moving to a parliamentary system. I mean, we need to have rules that allow the majority to govern.
