Republicans and Democrats that support earmarks keep up the mantra that their accepting bribes is good for their states and eliminating earmarks won't save any money.
It's not the money, it's the process. It's not how money will or will not be saved nor whether it is spent by Congress or whether it empowers the executive branch to spend the money as they want for political purchase.
It is about bribery.
If they still don't get it then they are too stupid to be in Congress. Earmarks are simply a symptom of the larger broken process in which government works and how legislation id passed. Bribery, tit-for-tat, backscratching or reaching across the aisle, whatever you call it, it is an evil that has grown to proportions that match the proportion in which government has grown.
If these bagmen still don't get it then have them study the Louisiana Purchase and the Cornhusker Kickback.
Stop the bribery. Stop Earmarks.
