an over-representation of factual presentations...
He doesn't say an over-representation of the facts, or of statistics, or any such thing. The key word here is "presentations." He's talking about disproportionally talking about the the issue; not altering the content.
And believe me, I know what a liar he is. Let's just make sure we hammer him about actual lies. We've had enough grief from leftists who don't know what constitutes a lie.
Baloney. The key WEASEL words are, "dangerous, solve, and "crisis." There is no dangerous crisis therefore there is nothing to solve.
Gore: ".... I believe it is appropriate to have an over-representation of factual presentations on how dangerous (global warming) is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis."
Liars lie and only other liars or dupes agree with them.
You have a decent argument that Gore isn't lying THIS time; however, this is politics. It looks enough like a lie for it to be used to advantage. Gore could have said what he meant in a more precise manner. He failed to do so, and should be made to pay the price by the dilution of his message.
Disagree. If that's what he meant, he would have said "an over-presentation of ...."
Don't help him slick his way out of this.
