Of 27 past inaugural crowds I could find, Ronald Reagan in 1980 and George W. Bush in 1993 were the biggest by a Republican president at 500,000. Ironically, Reagan’s second inauguration was forced inside by frigid weather and the parade cancelled. Bush wasn’t re-elected.

Democrat Barack Obama’s 1.8 million in 2009 is the all-time leader. Lyndon B. Johnson’s 1.2 million in 1965 was more than double John F. Kennedy’s 500,000 in 1961. Obama’s second inaugural in 2013 drew 1 million while Bill Clinton’s saw 800,000 in 1993.

Kennedy ushered in the modern era of large inaugurations. Abraham Lincoln’s first inaugural in 1861 drew only 30,000. Considering the city’s population was 20,000, that’s pretty impressive.
