Republicans
One thing you can say about Republicans is that it's difficult to compare today's crop to the pre-Clinton Republicans. It appears to me all they're interested in is blocking anything the Democrats propose regardless of how good an idea it is. They've gone so far as to vote against their own bills when Democrats agreed with them. It borders on treason when you hear someone like Mitch McConnell say his number one job is to make Obama a one term President. That sounds to me like it's more about political power than running a country.
The Post Office's retirement plan suffers from a Republican passed law that requires them to fund the health care for retirees for the next 75 years (more like 70 now) by 2016. That means they're funding retiree health care for people that haven't even been born yet. To me that's just a Republican jab at the Post Office as the largest unionized employer in the US.
