Out of the 46 presidents of the USA, 14 were Master Masons. One more (LBJ) had been initiated as a 1° Entered Apprentice, but he never completed his masonic journey. That is over 30% of all the presidents in the history of the USA. Considering that the average masonic membership of the USA male population has been between 1.25 and 3%, that demonstrates a significant influence on the highest levels of political power.

George Washington (1789 – 1797)
