A palinista is a severe loyalist who still supports the failed 2008 VP candidate, denying all evidence and logic that she was a complete fool and humiliating disaster. They are mostly evangelical supporters of creationism and refuse all proven scientific knowledge. Their philosophy is "Don't confuse me with the facts, my mind is already made up".
When my father parroted the FOX Noise line that Grandpa John hit a home run in the selection of the VP for the 2008 republican presidential election, I told him that he hit a weak grounder right to the first baseman, and he refused to talk to me for a month. He will be a palinista until the day he dies.
