Jon Stewart sat down with author Scott Miller to talk about one of our more forgotten presidents on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central). Miller thinks William McKinley is overshadowed by his successor, Teddy Roosevelt, but McKinley led this country through a very pivotal time in our history.

His legacy as a president, according to Scott and worded by Stewart, is that "his warring ushered us into the Imperial Age."

But the best part was how diplomatically Scott phrased our international holdings and presence after McKinley. "He really introduced America to foreign affairs and provided commitments for us."
