An endorsement of Trump on terror from...Piers Morgan???? Piers a stoutly liberal media personality. When he clearly takes shots at Clinton and Obama, you know he's sensing which way the wind is blowing. It's in his best interest to be on the right side. Equally, he clearly has to be considered in his opinion to go against liberal orthodoxy on this issue. Perhaps his own views have, to borrow an Obama term, 'evolved on this issue'.
Hillary Clinton has shockingly turned unfavorable in the resolutely liberal California. While she is in no danger of losing the state, it is clearly a sign of a problem.
