Arizona used to be firmly Republican, but now it's a battleground state as its politics and demographics have changed. And, voters heading to the polls may be feeling anxious, with all the talk of possible violence. But with the rise of hate crimes during the Trump administration, there are many Americans who have been feeling that way for the last four years. Also, the US will officially be out of the Paris climate agreement on Nov. 4. How long it remains out will depend on who wins the election.
