Hannity has been trending in that direction for a number of years.
Keep in mind that Hannity has been bought off by Saudi Money. For him it's all about keeping the income flowing, and he will continue to serve his Saudi masters well.
I just heard the interview from yesterday, and Hannity's obsession with the difference between islam and "extremist islam" was laughable, and ultimately sad and pathetic.
He is no longer on our side. We need to synthesize that into our worldview so we can move on to more pressing matters at hand.
