"There are no great limits to growth because there are no limits of human intelligence, imagination, and wonder." - Ronald Reagan

Ronald Reagan's legacy is invoked constantly in American politics today, whether to highlight conservative ideals or presidential leadership traits. So in the newest episode of the Presidential podcast, we decided to take a look at how well the popularized image of Reagan aligns with the man and the commander-in-chief he really was.

Our guest for the episode is Lou Cannon, who served as senior White House correspondent for The Washington Post during President Reagan's administration and who has written several books on the Republican icon, including the acclaimed biography "President Reagan: The Role of a Lifetime."
