This says it about right

From Lance Mannion via Atrios:

If the Government is a car setting out to give every one a ride to work, then for 40 years the Republicans have been puncturing the tires, pouring sand in the gas tank, stealing the distributer cap, and, whenever they can get their hands on the wheel, driving it straight into the nearest ditch and then, pointing to the wreckage as the tow truck backs up to it, saying, See, this proves that people were meant to walk.

And they do this so that they don't have to chip in on gas.
