Im sure that the people who call themselves true "conservatives" are voting out of principle or some other nonsense like that. For that matter, the evangelical types would be starting a third party now if it wasnt for Huckabee.
But you right...the pendulum is swinging back again..we've had 25 years of conservatives in some form or another in charge in DC. When Reagan came in and you were on the receiving end of his largess on taxes you did well...and when the other guy lost his job..you would think.."gee thats too bad " get in your BMW and go home.
The Reagan revolution as its called was rapidly overtaken by excessive greed. Now that other guy is you..and you take stock...after 25 years of crumbling public infrastructure, schools, medical care industrial infrastructure..you name it and still the "new idea" is to continue to make the government local state and federal so ineffective as to become a campaign issue. They are simply grabbing whats left and riding the train until it stops. So much for patriotism.
