Here's my conversation with Ralph Begleiter (formerly of CNN, now director of the Center For Political Communication at the University of Delaware) about tomorrow night's presidential debate. I asked him:
- how important avoiding gaffes will be for the candidates;
- the impact of Twitter and other online media on the campaigns;
- the history of debates affecting the final outcome of previous elections;
- whether Obama or Romney will go after moderator Jim Lehrer (as Newt Gingrich did earlier this year, attacking John King).
