I will admit to a tendency to nitpick at polling methodologies, but it does make me a tad skeptical to see that this poll had a greater sample of Democrat men than Republican men. That might be true in San Francisco or Manhattan, but in damn few other places in America. Also oversampled, demographically and as a percentage of registered voters: women and minorities.
The leading nature of the inquiry also served to "push" the desired response. A President cannot be impeached except for Constitutionally-defined reasons, loosely stated as they are. So what is the point of asking, other than to attempt to validate the media's obsessive hatred for the President?
In sum, it is the usual liberal media crapola, masquerading as "news".
