Like it or not, Hannity (and a few others like him) have become some of the most prominent voices in the conservative movement. He reaches millions of people every day with his radio program and millions more at night on Fox News.
Complacency on the part of the liberals is one of the reasons we conservatives were able to win so many of the great intellectual battles of the last 30 years. When I see conservatives lifting up a Sean Hannity as our "champion" I wonder if we aren't doomed to the same fate as those we once defeated.
