The coolest Republican is Adam Kinzinger - who most of the party considers to be a RINO...
On the other hand, the most beloved figure in the party is a twice-impeached ex-president who was so bitter about his loss he refused to expect it and tried to have his cult invade the capitol of his own country. Less cool, and more concerning/disturbing/psychotic.
What about Schwarzeneger?
Very true, but both Kinzinger and Shwarzenegger are considered RINOs at this point. Ironic that two of the coolest and best figures left in the party are so disliked and distrusted there.
Kinzinger is not 1/10 as cool as Arnold
