Gingrich was an avid proponent of the impeachment of President Clinton. His stance was not that the President was an adulterer, but rather, that he lied to investigators and lied to the american people. Nonetheless, he is already being referred to as a hypocrite by liberals, moderates, and even some conservatives in the blogosphere. I do not agree with this sentiment.
I can no longer support his as the candidate of choice, since his pursuit would only revisit the impeachment hearings, and would inevitably portray him as a hypocrite. Nonetheless, I think his presence and insight into the race will be of benefit to conservatives. With a man like Newt, clear-thinking and always conservative, in the picture, it will force others in the race to take their conservative constituents seriously, and won't be as willing to represent moderate or liberal positions (Guiliani).
