Yeah, I think Huckabee is live the same time as Rush. Having Ramsey on WJNT will probably be a new experience for those listeners and Huckabee on Supertalk will be something new for those listeners, so it's probably beneficial for the swap.
I do agree with X-Broadcaster, though: Ramsey's show gets old once you've listened for a short while. But as long as he keeps fielding called that are tens of thousands of dollars in debt, I guess he'll be able to keep plugging away at his basic rules and continue being a success.
