The sprawling state of Arizona was once reliably Republican but in 2020 that changed.
Joe Biden became only the second Democrat to win here since 1948, winning by less than 11,000 votes, and polling suggests Arizona could once again be won and lost by the narrowest of margins.

Many of the people there to watch the Friday night sunset were contemplating a consequential decision.
Those include Jennifer Montero and her fiance Richie Garcia, who say their vote on Tuesday is based on their economic circumstances.
“Prices have gone up like crazy,” said Ms Montero, “and then, especially now that I’m wanting to get married and have kids, I definitely want to be able to go to McDonald’s and afford a spicy for a dollar like they used to be.”
The couple are of Mexican descent, in a state where one in four voters are Latin American and the debate about immigration is complicated.

For Mr Garcia, being born in America means the border is less of a concern.
“Times are changing. I think a lot of the Hispanic community was very inclined to vote Democrat due to immigration status, but my parents are citizens. I believe that immigration status doesn’t really matter to me much anymore,” he said.
Less than 30 minutes away in downtown Phoenix, people were already beginning to vote at a drive-through polling centre.
One of them was Renee Rojas, a lifelong Republican voting Democrat for the first time.
Ms Rojas, who is of Native American and Latino descent, says that decision is down to Donald Trump.
“Recent rhetoric and the changes of the Republican Party just made me realise that things are not going the way they should be,” she said, before adding, “My mom, my grandmother is a Republican. She’s Navajo. You know, my other family members and friends, they’re all Republicans, but half of them are voting Democrat this year.”

Ms Rojas’s thoughts on the prospect of trouble after the result are a reminder of the strong Conservative values of the state she lives in.
“I’m an Arizonan. I have a gun myself, I have several different kinds of firearms, heavy machine guns and handguns. So I am a proud gun holder and people will demonstrate the way they want to as long as they’re not hurting anybody.”
For other drive-through voters like Peter Orozco, the choice was a simple one, about stability.
He feels the current administration will maintain the foreign policy status quo.
“We can’t politically make any big changes, especially on an international scale, you know, because if we get somebody else president other than what the existing presidency is, it could be World War Three,” he said.
In Arizona, there are other voters who feel the state is worse off since the Democrats came to power.
They include Dane Jensen, a 26-year-old mortgage broker.
For the last few days, Mr Jensen has been standing outside another polling station in Scottsdale with a “Swifties for Trump” banner.
He made the banner as a joke to try to ruffle the feathers of people voting for the Democratic party, which the singer has endorsed.

About Swift, he said: “That’s like someone like that who has a private jet and is flying around the country who is, in my opinion, creating more fossil fuels and bad energy for the environment than any one person.
“And for you to sit there on your high horse and billions of dollars, and tell people what you think should happen when you’re already set for life, I don’t really agree with that.”
