——Which one is it?——
It is neither.
To equate radical conservatism with being a Republican is erroneous. The vast majority of Republicans are not conservative firebrands. That is not to say they can not be called conservatives.
Your thinking is best described as RINO Creep.
I like that ‘RINO Creep’ concept.
To those that somehow think that adhering to the U.S. Constitution is radical conservatism, I say measure yourself on yardstick. One side touches the U.S. Constitution while the other side touches the progressive notion of a Living Constitution, which is just another fancy term from Democrats who adjust the U.S. Constitution to match whatever political agenda they are advancing at the moment.
I, myself, as a conservative, am on the side of the U.S. Constitution. RINOs are somewhere in the middle, and the Obamanation is on the far side of me.
So when you take the measure of a man, think of this yardstick. Should America creep down the yardstick to the Obamanation side or should it be firmly on the side of the U.S. Constitution?
Quoting Dwight D. Eisenhower, “I have one yardstick by which I test every major problem - and that yardstick is: Is it good for America?”
