A citizen would have to be awfully naive to expect strict fidelity to the truth from any politician, much less a presidential candidate. As a thought experiment, however, it’s interesting to wonder how an epic prevaricator like Mitt Romney would handle the presidency.

See, when the president says something crazily at odds with reality, everybody notices. When he makes an obvious blunder, like President Obama’s assertion that “the private sector’s doing fine,” voters take heed. Too many, and his credibility’s shot.
