An Arizona political watcher says Donald Trump has just crossed the line with his call to ban all Muslims from entering the U.S. Michael O’Neil with O’Neil and Associates goes so far as saying ,”the seeds of destruction have been sown” on Trump’s campaign, but the unraveling won’t happen overnight.

Further, O’Neil predicts rival G-O-P presidential contenders will take “the Donald” to task on his sweeping proposal in the next debate. An array of candidates from Jeb Bush, John Kasich Rand Paul and Lindsey Graham have already denounced the remarks in their outrage. Arizona Republicans such as Senator Jeff Flake say, “just when you think he can’t stoop any lower, he manages to do so.”

O’Neil says if Trump ever got into a position to order a Muslim travel ban, it would be struck down as unconstitutional, even from the “most conservative court.” But O’Neil won’t deny the likelihood of another homegrown terrorist action, like the San Bernardino massacre, from occurring in the U.S.
