Many people say there is no difference between Democrats and Republicans. Yes, well, there are some minor ones I happen to like.

Also, some conservative sites keep railing on Rep. Joe Murtha. Granted, the guy made a pretty big mistake, but let's review what the arguments would be if he were a Republican:

- This happened 25 years ago, give it a rest! The fact that it's in the news proves the liberal bias of the media.

- He was never found guilty for any wrongdoing.

- It was a mistake he made early in his career; getting embarrassed like that would make him more ethical because he learned the hard way what a mistake like that can cost him.

And so on. Feel free to add any other excuses that would be used by the GOP were it one of their cronies.
