Rush has everything to gain and nothing to lose as A highly paid entertainer by not endorsing, or even stating his favorites.
That way he can avoid embarassment from a slip by a favorite, leaves him to say positive and negative things about everybody.
It is related to but not the same as Palin and Gingrich still undeclared about candidacy.
People ought to recognize it, because Gingrich did it before.
The list of GOP potentials is ridiculously long, at this point. Over and over Romney, Huckabee are at the top, followed by Gingrich and Palin.
Romney is sooooooooooo rehearsed and coiffed that he looks like the bionic candidate.
But he is leading, until something takes him down. I cannot imagine him escaping very serious opponent research, for skeletons.
Huckabee cannot control his appetite, and finds no time for exercize, now that he has a big media income. Bloating up fast.
I see Romney winning of the top four. So it defaults to the huge group of single digit possibles, for any opposition to Romney.
