Pollster Peter Hart, who with Bill McInturff does the
NBC/Wall Street Journal poll, says "Gingrich is Goldwater." By this he means that Gingrich would lose big and drag down much of the rest of the ticket. A
National Review Online article by Jim Geraghty is the
source.
There could be truth to this claim. Gingrich pronouncements please the Republican base but may antagonize independents and energize both them and Democrats to vote in opposition. At least that is the theory.
