Lyndon B. Johnson
A successor to JFK, Lyndon B. Johnson obviously had large shoes to fill. His IQ of 140.6 was undoubtedly involved in his decision to increase America’s military presence in Vietnam. Perhaps, he should’ve asked for Woodrow Wilson’s advice before signing off on that one. On a lighter note, Johnson was known for his unapologetic ‘bathroom interviews,’ refusing to allow journalists to get between him and his time on the throne.
