Gallup polls going back decades show precious little shift in established voter trends before and after debates.
…there are relatively few examples of times in which the general election presidential debates fundamentally altered the course of a race.
Presidential debates rarely have much effect on election outcomes.
It’s nice to see these, rather than hype about the debates as “game-changers.” Maybe political science is “killing the campaign narrative” after all?
UPDATE: Add John Harwood to this list.
UPDATE #2: And Mark Barabak.
