Newt Gingrich's appearance on Meet the Press was aimed at one audience: Hard core Republicans who view the Bush administration as both incompetent and traitorous to key Republican values. Gingrich talked tough on Iraq, used a plethora of references to Ronald Reagan (a sure sign you're talking to misty-eyed conservative ideologists), and had, well, pretty much all the answers.
Middle America probably loved it.
Two problems jumped out, however:
1. He was long on proposed solutions, but didn't account for any sort of political opposition. DeTocque will happily throw out 20 proposed changes to "Win in Iraq", but it's the EXECUTION of those things which seems to get everyone in trouble.
2. If he does decide to run for President (which will probably be determined by poll numbers based on appearances like this), he WILL fill a void amongst Republican candidates, but he WON'T get very far: when push comes to shove, he'll lose out when his opponents keep bringing up that nasty affair he had while leading the impeachment charge. He might talk the talk, but the evangelicals will have their say...
