Right, like the PUBs did when LIBs were screaming “Bush lied, people died”.
Personally, I prefer the tactics of that guy in Ohio who disrupted the LIB candidate with repeated cries of “Liar”. Facts are great; but remember that you are trying to convince people that have the attention span of a flash bulb. No time for niceties.
The only nicety I’m willing to indulge is to answer where were you when Bush was doing the same thing. Answer: I spoke up; but no one listened.
