Hillary Clinton is officially ahead in the polls in Arizona. Trump has been leading Clinton by only a few points the past month in the historically red state, but Clinton now trumps.

Clinton is leading by 5 points. This is a historical moment in politics because Arizona has not voted blue since the 1996 presidential election when Bill Clinton took home the 11 electoral votes.

The Clinton campaign is investing $2 million into advertising in Arizona. There are 20% of undecided voters that she hopes to win.
