Between 1865 and 1901, three American Presidents (Lincoln, Garfield, McKinley) were assassinated. In 20th century terms, that would be equivalent to Kennedy, Reagan, and Clinton dying by assassination. That would cause 20th century people to freak out. What was the feeling toward this in the 1800s?

To add on to this question, to what extent would the freak out (or lack thereof) be tied to the president's popularity? i.e. OP cited JFK, Reagan, & Clinton as possible presidential assassinations, but these are 3 supremely popular American presidents; Lincoln obviously has a certain legacy to him, but would Garfield or McKinley be more akin to a Jimmy Carter or Lyndon B. Johnson, thus setting off different reactions upon their assassination(s)?
