A poll of likely Arizona voters released on Monday shows Hillary Clinton leading Donald Trump by a single percentage point.

Clinton leads with 40 percent, followed closely by Trump with 39 percent.

The one-percent lead by Clinton is well within the poll’s margin of error of 3.63 percent.

Libertarian Party nominee Gary Johnson places a distant third in Arizona in the Monday poll.

Green Party candidate comes in fourth place with a negligible one percent.

After well over a year of essentially constant news about the 2016 election, 13 percent of Arizona’s voters say they have managed to remain undecided.

OH Predictive Insights, a subsidiary of Phoenix-based Owens Harkey Advertising, produced the poll.

“Donald Trump continues to slowly increase his numbers, coming to a near virtual tie here in Arizona,” OH Predictive Insights chief pollster Mike Noble said in a statement sent to The Daily Caller.

“Hillary Clinton’s Democratic vote is more consolidated compared to Donald Trump’s Republican vote, 83 to 73 percent,” Noble added. “Surprisingly, the gender gap between the two candidates is nearly nonexistent in Arizona, with Clinton leading Trump by 4 percent with female voters.”

The poll is based on a combination of automated phone calls and live calls to 728 likely Republican, Democrat, independent and undeclared voters. About a quarter of the calls were mobile phone calls. The remainder were landline calls.

Voters in Arizona have chosen the GOP candidate four consecutive times — and nine times out of the last 10 elections. The one time since 1976 when Arizona voters chose a Democrat was in 1996. That year, Bill Clinton won the state on his way to a second term.

“Typically, during an election year, Arizona gets little-to-no attention in a presidential contest but this election year appears to be an enigma,” Noble said in the statement sent to TheDC.

On the website FiveThirthyEight, celebrity pollster Nate Silver gives OH Predictive Insights a C+ rating. That’s on the low side, but many polls don’t make Silver’s cut at all.

Arizona will provide 11 electoral votes to the presidential candidate who receives the most votes in the state on Tuesday, Nov. 8.
