Having covered every White House race and convention since 1972 hasn’t appeared to calm Bob Schieffer’s nerves when it comes to the presidential debates.

CBS’s “Face the Nation” host is poised to serve as moderator Monday night at the final debate between President Obama and Mitt Romney, in Boca Raton, Fla.

When ITK caught up last month with the veteran newsman, who moderated two previous presidential debates, in 2004 and 2008 — he explained his biggest fear about his role: “You know, I had this dream once, where it was before the 2008 debate, Barack ObamaBarack Hussein ObamaMcCarthy: ‘No deadline on DACA’ Democrats will need to explain if they shut government down over illegal immigration Trump’s first year in office was the year of the woman MORE and John McCainJohn Sidney McCainMcCain rips Trump for attacks on press NSA spying program overcomes key Senate hurdle Meghan McCain says her father regrets opposition to MLK Day MORE. And in my dream, I said, ‘Well, gentleman, that’s all the questions I have.’ And I looked down and I had another half-hour to go!”

Schieffer, 75, added with a laugh about the final debate of the election season, “So I guess that’s my worst nightmare. But don’t worry, I have plenty [of questions].”

The Texas-born political journalist calls the debates “a good thing,” saying, “Our politics are so polarized now that when you can get people from both sides to watch the same event, it’s kind of a neat deal.”
