Conant gained his first experience in the political sector during his time at high-school. In 1996, he volunteered for Rudy Boschwitz's Senate campaign and subsequently served on Norm Coleman's mayoral re-election campaign in 1997 and on his race for governor of Minnesota in 1998. After graduating high-school, Conant deferred his university entry, to continue serving on the campaign of Coleman until 1999 and while at university, he then served on Coleman's 2002 U.S. Senate campaign. Following his time at university, in 2005 Conant started serving as press secretary for Senator John Thune of South Dakota and in 2006 he became deputy press secretary for the Office of Management and Budget and then served as a White House Press Secretary for George W. Bush. In 2008, following his time at the White House, Conant then served as the national press secretary for the Republican National Committee. Campaigns and Elections commented on his time at the RNC "If you're a reporter in Washington, you know Alex Conant. As the RNC's national press secretary during the 2008 election, Conant waged an assault on the media's e-mail inboxes—but he did it in a friendly way."
In 2011, Conant was hired as a spokesman and advisor to Marco Rubio, for whom he served for over five years. He first worked as press secretary in Rubio's Senate office before he joined the presidential campaign. He later also served as a senior advisor on Rubio's Senate re-election campaign.
In 2014, Conant served as a senior advisor on Joni Ernst's 2014 Iowa senatorial campaign. Together with his wife, Conant was sent by the National Republican Senatorial Committee to support Ernst towards the end of her campaign. Politico commented "two respected Capitol spokesmen with presidential campaign experience" had been sent to support Ernst and Conant, who was still working for Rubio, stated: "As you know, Marco was an early supporter of Ernst and his team is doing everything we can to help out. It'll be great to have a woman, soldier, and independent leader like her in the Senate."
In March 2015, Conant moved from Rubio's Senate office to his Political Action Committee, and in April was officially announced as the presidential campaign's communications director and subsequently served as the campaign's senior spokesman. Conant made headlines when in March 2016, CNN cancelled an interview with him, after he had criticized the network's report that Rubio's campaign was debating to suspend operations. He also helped Rubio make a strategic turnaround, regarding his position on immigration reforms and later served as communications advisor for Rubio's 2016 U.S. Senate campaign.
