If Hannity volunteered to do it, especially as a charity fund-raiser for the troops, then he will do it. He might take some time to set it up to make it a big event and raise as much $$$ as possible, but he wouldn't back out on it. Even if he turned chicken, the credibility cost would be WAY too high.
Regardless of his politics, he is consistent, and generally willing to put his money where his big mouth is. Personally, I can't stand Olbermann, and would love for Hannity to go for a couple hours to totally drain Olbermann's finances -- but KO would probably weasel out after about five minutes.
I don't think any of this is correct.
