Dont forget Clinton and both Bushes.
Clinton? i don't think so
as for the Bushes, no they are not. here's qoute from 'americanpresidency':
"George Bush has also sometimes been referred to as Mason. But, neither he nor his son, George W. Bush, are Freemasons. The confusion as to President Bush arises from the swearing in ceremonies at his inauguration. He took the oath of office on the George Washington Bible which belongs to St. Johns Lodge in New York City. Because the Bible belonged to a Masonic Lodge many writers assumed he was a Freemason".
