That tagline comes from a local radio host. He's been on the forefront of conservative talk radio for 10 years. He and Rush used to work together here in Pittsburgh.
It's the Quinn in the Morning Show with Rose at 104.7 FM or on the web at www.warroom.com in archive form.
And when you think about it, he's absolutely right.
I'll be nitpicky here since you're referring to your tagline (which is great, by the way) -- there should not be an apostrophe in "its". Only when it is used as a conjuction of "it is" should it get an apostrophe.
I feel like messages get watered down when there are grammatical errors. Not that we don't all make them (in fact I've probably made a few in this post, like this sentence fragment!).
