Everyone is disliked, I know Hannity is by some but..
Hannity has a pretty good name all the same, he's pushed this, Newt Gingrich seems to have mentioned it. They are putting their names on the line and they'll really look silly if there is nothing to this. To me, Hannity would lose virtually all credibility if this story has no legs.
Some of these people might know things we don't.
