So, let me get this straight. The Tenth Amendment of U.S. Constitution* is "doctrine" that a candidate for the 2012 (that means post Tea Party America) GOP POTUS nomination should NOT be "preaching" to the electorate?!
You aren't Rich Flowry, are you?
* The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. ... the 10th Amendment to the U.S. Constitution
Good luck with that. Preaching to the choir doesn’t win elections. You need to broaden your appeal by appealing to normal people.
That’s not to say give up your principles. Don’t get confused. It means talk about real world things letting your principles animate your words. Don’t just preach the doctrines or regard them as a panacea.
If the American people understood or demanded a 10th amendment style gov’t they would have one. We have to lead by example to get there.
