Eight items were promised on the first day by the Republican majority after the 1994 Congressional election.
The first item on this list is"Require all laws that apply to the rest of the country also apply equally to the Congress." This is an interesting campaign promise and one that was not particularly hard to keep either.
Realistically this promise has been kept in my opinion. Congress is part of the Federal Retirement System. They pay Social Security Taxes but are treated as Federal employees.
I certainly wish that Congress was part of the failing Social Security System like the rest of us; but, they are not. I think that if their retirement benefits were paid out by Social Security they would have more of a vested interest in fixing Social Security.
That being said, Congress has a comparable retirement system to many Federal workers. So, in my opinion, The Republicans have basically kept this promise. So the score is:
