President-elect Donald Trump won Arizona, NBC News projects, putting him in the 11 electoral delegate vote column after narrowly losing the state to President Joe Biden in 2020.

Trump’s expected victory over Vice President Kamala Harris comes after years of shifting political landscape in the Sun Belt state, following Trump’s 4-point victory over Hillary Clinton in 2016.

Since then, the state once tightly controlled by the GOP has installed a Democratic governor, two Democratic senators and other statewide elected officials. A rapidly growing Latino population and a revolt against Trump among some former Republicans have put the once-red state in a battleground state. And Biden’s 2020 victory in Arizona was the second time in 28 years that Arizona’s electoral votes went to the Democratic presidential candidate.

Yet most of these Democratic victories were achieved by very small margins. Arizona was the nation’s second-closest state in the 2020 presidential race, with Biden trailing Trump by just 0.3 percentage points (10,457 votes).

The state subsequently became the epicenter of Trump’s post-election spread of baseless conspiracy theories that the election was stolen from him; Republicans in the state eagerly embraced these claims, and some of those Republicans failed statewide in the 2022 midterm elections.

But in the 2024 presidential race, polls over the last few months had given Trump a slight lead over Harris in Arizona, but were still within the margin of error overall. But while Trump’s campaign in Arizona was largely outspent and better organized than Harris’ campaign, Republicans saw a surge in voter registration heading into the presidential election year.

And the state was a good fit for two issues central to Trump’s campaign: the economy and immigration.

This summer, Arizona saw some of the highest gas prices in the country, and both Harris and Trump also made visits to the Arizona-Mexico border during their visits to the state. Still, Arizona was among Trump’s least-visited battleground states and was geographically separate from most other battleground states.
