I heard about half of Rush radio today, and he seemed to be defending Trump against the GOP elites today. I think he is beginning to see the picture on the wall, that his chosen candidate is not going to make it. Rush will ALWAYS get behind the winner, in every election. I still remember he became pro-Romney as soon as Romney became inevitable.
That picture is of El Rushbo's rating. Once Trump is nominated, Limbaugh will be Trumps biggest fan.
