Biden spent big in the newly minted battleground state, with the Phoenix media market often soaking up more money from his campaign than any other in the country in the final months of the election. Trump’s strategy appeared more geared to revving up his base than wooing on-the-fence swing voters, taking a turnout approach to defending Arizona once it became clear it was one of the most vulnerable targets for Biden to flip this year.

In the final days of the campaign, Trump visited parts of Arizona where he had strong support, holding packed rallies, despite the coronavirus pandemic, as he tried to turn out more conservative voters.

Biden’s campaign dedicated most of its efforts to Maricopa County, driving up turnout among Latinos by promising to better handle the coronavirus pandemic, which has disproportionately impacted Americans of color.

Grassroots Latino groups and union organizations were a key piece of Democrats’ field organizing, with some starting door-knocking programs in August despite the Biden campaign’s reluctance to do so during the pandemic for most of the campaign.

Despite Arizona’s competitiveness, Biden only visited the state once during the general election as he restricted his travel during the pandemic, a point of contention among some on the ground.
