Only a liberal would lie about something they said, even though the something they said had been shown on television and videotaped for the ages. I guess that's because, for liberals, lying has proven to be a very successful strategy. In fact, it's their only strategy.
They don't thinkof it as lying.
For liberals, truth is whatever serves them at the moment, and a lie is whatever doesn't. It's the old Communist credo, "Truth is whatever serves the party."
