Common sense has no source.
Obviously Glenn Beck is not going to admit that he's a closeted Romney supporter who must hide it so that he does not lose his listeners (many of them Christian conservatives) who may think he's for Romney only because they share the same religion.
He's just not going to let that out of the bag anymore than Rush would let it be known who exactly he supports in the primary. Only difference is, Rush Limbaugh is honest with his listeners. Rush told them he's not going to say who he is for.
Thanx for confirming you have no facts.
