Looking for a metaphor for American politics? Try Charlie Brown trusting Lucy not to pull the football away as he races to kick it.
In 2008 the American voter played the role of Charlie Brown and the Democratic Party played the role of Lucy. The football was Change We Can Believe In. Yes, we believed. And then Lucy pulled the ball away and we found ourselves flat on our backs. This year the American voter is once again playing Charlie Brown while Lucy is played by the Republican Party. The football is still and always Change We Can Believe In.
Is anything going to change come January? No. Why? Because Lucy is Lucy regardless of who plays her.
