Any departments not mandated or enumerated by the General Welfare clause of Article I, Section 8 of the U.S. Constitution SHOULD be eliminated as unconstitutional. Bush may have been a Republican but he was no conservative. Reagan attempted to eliminate the Department of Education but was blocked by Democrats in the House.
See my previous post when it comes to Democrats (specifically in the Senate) being permanently attached to the teet of government.
If you are so against government entitlements, please feel free to call your rep and tell them you want 0bamacare repealed.
