Colorado Tea Party information:
Contact information for some of the April 15 Tea Parties on the Colorado Front Range is here, on the website of the Colorado Union of Taxpayers (of which I am a member of the Board of Directors). Note that this is a non-exclusive list; I believe that there are also Tea Parties in Grand Junction and Colorado Springs.
As you will see, the state legislature's Republican Study Committee is climbing aboard the Tea Party bandwagon. The RSC chair, Senator Kevin Lundberg, has a strong record on taxpayer issues, compiling the 3d-best rating of any Representative in 2008.
