Constitutional Party

I understand that there is a Constitutional Party which believes in a strict interpretation of the Constitution as written by the founders. I wonder how one joins? In a previous entry I lamented the expansion of the federal government using the interstate commerce clause and the general welfare clause of the Preamble. Note what two of the founders had to say on the matter.
"If Congress can do whatever in their discretion can be done by money, and will promote the general welfare, the government is no longer a limited one possessing enumerated powers, but an indefinite one subject to particular exceptions." James Madison
"Congress has not unlimited powers to provide for the general welfare, but only those specifically enumerated” Thomas Jefferson
We're probably too deep into the stretching of the Constitutioonal provisions to get out completely, but it's not too late to return to the original intent in future actions by the President, 'Congress and the Courts.
