Since when did Arizona become a swing state? Since Donald Trump became the Republican nominee for president.

To get a full measure of the recent free-fall of the Donald’s campaign, look no further than the home of former GOP White House hopeful John McCain. At the end of July, the psephology site FiveThirtyEight.com had odds of Trump winning the Grand Canyon State at a robust 75 percent. A little over a week later, the odds have shifted dramatically, and are now in Clinton’s favor, 53 percent to 46.
