The Arizona Democratic Party has officially endorsed Senator Mark Kelly as a potential vice-presidential nominee to run alongside Kamala Harris, supported by organizations advocating for voters of color. However, Arizona Democratic Party chair Yolanda Bejarano emphasized that the final decision rests with Harris, who is considering several candidates, including Kelly. Kelly's ally, former state senator Raquel Terán, also endorsed him, highlighting his outreach to Latino communities and belief that he would bolster Harris's campaign against Donald Trump. Despite previously not supporting the Protecting the Right to Organize Act (PRO Act), Kelly recently expressed his commitment to vote for it, addressing concerns from labor unions regarding his candidacy. His stance on labor issues is crucial, as unions play a significant role in the Democratic coalition. As the political landscape evolves, Harris has gained the backing of Arizona's DNC delegates, further intensifying speculation about her running mate choice.
