The reason the "Tea Party" is under such concerted attack from both elected Republicans and Democrats is that they (possibly) do not share these fundamental premises, which are the foundation of the post-1933 American state.
The elected Republicans, and the Democrats, also share the belief that even a reduction in rates of increase in "programs" will trigger violence on an almost unimaginable scale.
The reason they don't do what normal, psychologically healthy people would do under threat - say, "Bring it on and we will shoot you down in the gutter" - is because elected Republicans and Democrats also share the belief that socialism is basically RIGHT and that capitalism is fundamentally WRONG.
So, it is wrong to say that the Republicans are "folding" - they do not share your fundamental beliefs and they never did.
They are just doing what they must to keep their dying world alive for a few more years.
BINGO! And they’re world in one of lavish trips and high society living and a stuffed retirement system. All of them want that to keep going as long as possible. If the country folds, their gravy train is the first one off the tracks.
