On Saturday morning, I was reading about Theodore Roosevelt’s campaign in 1912 and watching archival videos of the 1992 Republican National Convention (RNC). The latter opened with Ronald Reagan’s last convention speech, a victory lap for the man who won the Cold War.

Before sundown, Donald Trump had joined Roosevelt and Reagan as Republican presidents who survived assassination attempts. That will influence the RNC unfolding this week in Milwaukee, the very city where Roosevelt was shot in 1912.
