I think you have got it!!! I would hazard to guess, from living here in PA, that this will not blow over quickly...and Arlen, thru his own sense of self importance, may have lost the position...too bad. He might even switch parties...again, too bad. The fact that he (Mr. Magic Bullet) is still restating and revisiting his position (and this is Sunday--his Opus was released on Wedneday) means he got an earful...from his fellow R's, maybe from the WH, and now the 'little people' are speaking...
