Not automatically, but it means great lengths to prove it. Not every GOP president, but definitely the Bush administration now that it's evident that it was not conservative at all. And now that it's become clear most of the people in the administration who we thought were conservatives were left wingers masquerading as conservatives.
A famous conservative one said, "Trust but verify." You disagree?
So from Ted Cruz’s record you have concluded that he is another “left winger masquerading as a conservative”?
