Judging by the audience response to Gingrich's idea for Lincoln/Douglas-style debates, where the candidates can have substantive discussions on the issues, and effectively have a conversation with the voters without a 30-second buzzer, they are tired of the current asinine questions and format as well.
The media continue to think that the American people are stupid, and that they are the purveyors of truth and wisdom when it comes to picking who the President should be. The American people, though, are very well engaged and are well aware of what these debates are about. Many Americans say that they are sick of politics and the gotcha style of politics. Well, it is the media that continues to politicize everything, in the hope that in can catch a politician, or any other public figure, making a verbal gaffe on camera. or with a mic on.
Gingrich is climbing in the polls because he has had the guts in these debates to point out what many of the American people know, and opening the eyes of many others who are now seeing what political hacks many of these so-called "news" people are.
