Ron Paul is the most Constitutional Revolutionary of the modern era. Like many others on Mount Rushmore, he stands for individual liberty and freedom.
His consistent stance in congressional politics for freedom merits a spot next to the very founding fathers that he takes inspiration, and constitutes his views from.
No man alive today, has the ambition or veracity for freedom like Ron Paul does. This is why he should be on Mount Rushmore, because he shares the very American spirit that our founders fought and died for.
