"We have a two party system. The Democratic party - which is a party of no ideas. And the Republican party - which is a party of bad ideas. And the way it works is - a Republican stands up in Congress and goes, 'I GOT A REALLY BAD IDEA!' - and the Democrat says, 'AND I CAN MAKE IT SHITTIER!'
If that truly doesn't encapsulate the sum total of what passes for American politics these days, I don't know what does.
