I just received word from two mutual friends that David F. Nolan (known to many as either "Dave" or "The Nolan") passed away suddenly last night, two days shy of his 67th birthday.
An Arizonan since 2005, most recently Nolan was the at the top of the Arizona Libertarian Party's ticket, running a respectable and visible 3rd-party candidacy for the U.S. Senate. He was the principal founder of the Libertarian Party and also known for proposing what came to be known as the "Nolan Chart", one of several two-dimensional descriptors of political belief or tendency.
My sincerest condolences go to his wife Elizabeth.
I will follow up with information about the memorial service and where to send donations in lieu of flowers.
