Glenn has said many times he supports Rick Santorum. Before she left the race, he supported Michele Bachmann. He's consistently supported those two candidates from day one.
I remembber him being so pro Perry.
There is a 94% chance that Beck supports Romney regardless of what he is saying.
Gingrich has surged, he is trying to take him out.
Bachmann and Santorum have/had no chance of winning and Beck used that to say “see I’m not supporting Romney just because he is lds”.
There are historical an current mormon teachings that talk about the “white horse prophesies” which is that the Constitution will be hanging by a thread and ONLY a saint (lds) can save it.
Beck is (has been) clever so far in his support, it is evident that that cleverness is failing now that Gingrich is doing better than expected.
