FDR was in the 1930s. Do you remember Boehner, Gingrich, Tip O'Neill, Sam Rayburn. She is the first woman speaker. She will go down in history.
I feel like House speakers get remembered for a long time, particularly if they were effective.
It's the Senate majority leaders that start to fade for me. I have only a tenuous grasp on the memory of Trent Lott, Bill Frist, or Tom Dashle.
