less than McCain's margin
less than Romney's margin
But close.
Such is consistent with the results of the Presidential races of 2008 and 2012, at least in Arizona. If one wants to see Donald Trump win, then such is bad news at this stage. Trump must win Arizona; Hillary Clinton, like all Democrats since Harry Truman, can get away with losing Arizona.
But let's remember: Hillary Clinton has the Obama machine, the slickest Presidential campaign machine since that of at least Ronald Reagan, behind her. She trusts that campaign apparatus, one that Barack Obama gave the prerogative to say no to some quixotic attempt to win a State that he had little chance to win and that would put other states at risk of loss.
2008 and 2012 races just after the latter Party convention looked close. They did not look like the end result. Obama gained. He turned the race into one best described as a long-shot for a Republican victory and practically compelled McCain and Romney to make high-cost gambles to improve their chances.
