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 ObamaGOP lawmaker: Dems not standing for Trump is 'un-American' Forget the Nunes memo — where's the transparency with Trump’s personal finances? Mark Levin: Clinton colluded with Russia, 'paid for a warrant' to surveil Carter Page MORE and John McCainJohn Sidney McCainMcConnell: 'Whoever gets to 60 wins' on immigration Meghan McCain: Melania is 'my favorite Trump, by far' Kelly says Trump not likely to extend DACA deadline 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.”
