Am I saying that Centrists want to do away with the Constitution? No. I'll explain later. First, here is what Centrists are saying about the few Constitutionalists in Congress --
Margaret Thatcher died, and, compared to today's politicians in the US, she was a solid rock of principles, determined to beat back statism -- the Iron Lady versus the current bunch of Plastic Squishes, you choose. You'll hear a lot about Thatcher in the next few days, but you won't hear any analyses regarding our imploding political realm.
Centrists, Liberals and Progressives are rushing to the feeding trough in a frenzy to divide purchased voters while the nation's economy unravels. We're in a downward spiral similar to the one Britain was in when Thatcher temporarily conquered Leviathan and bought Britain more time to exist. All of Europe is presently re-learning the lesson Thatcher taught them.
In America, except for libertarians, Austrian economists, a few limited government reps in Congress and a few Tea Party organizations, we're ignoring all economic, Constitutional and liberty lessons. Those who promote free markets and limited government are outnumbered, and even in the GOP there are Teddy Roosevelt type Progressives like John McCain fighting against the few limited government conservatives. Libertarians are practically nowhere to be found in Congress. The Republican Party as a whole rejects libertarianism and Austrian economics.
Do GOP Centrists want to do away with the Constitution? No, they just won't consider it if it blocks their pragmatic political designs to assist the Democratic Party in maintaining State power. They'll save the two party, statist system at all costs.
