You're trying to put his statement into a different context now. I thought we were talking about him saying that he was totally against the war in Iraq, which he was. So we agree that wasn't a lie.

You can't disprove a hypothetical situation that never happened to call him a liar. Who knows what he would have done if he had been in congress instead of a businessman. It's clear though he was questioning it publicly as early as 2003 in the Cavuto interview, which was before the war started, and came out totally against it publicly in 2004 less than a year after it started. Who knows what he was saying privately before that. You don't know. This isn't grounds to call him a liar.
