Greenwald's Point

Leave aside the usual huffing and puffing. Can you answer this question for me:

Is there any other significant issue in American political life, besides Israel, where (a) citizens split almost evenly in their views, yet (b) the leaders of both parties adopt identical lockstep positions which leave half of the citizenry with no real voice?  More notably still, is there any other position, besides Israel, where (a) a party's voters overwhelmingly embrace one position (Israel should not have attacked Gaza) but (b) that party's leadership unanimously embraces the exact opposite position (Israel was absolutely right to attack Gaza and the U.S. must support Israel unequivocally)? Does that happen with any other issue?

Not that I can think of, off the top of my head.
