Senate Majority Leader John Thune, once a fierce opponent of President Trump, has emerged as a pivotal figure in advancing Trump’s domestic agenda. This transformation from adversaries to allies marks a significant shift in their political relationship.
This week, Thune played an instrumental part in the Senate’s approval of President Trump’s extensive tax and spending bill, setting the stage for the final vote in the House. Trump acknowledged Thune’s efforts, stating, “Thune has done an incredible job,” during a White House event in May.
Initially, Thune and Trump were at odds, especially following the 2020 election. Thune openly criticized Trump’s post-election conduct, calling it “inexcusable” in a 2021 PBS News interview, which led Trump to label Thune as weak. However, a pivotal visit to Trump’s Mar-a-Lago resort in March 2024 helped mend their relationship.
Lisa Hager, a politics professor at South Dakota State University, notes that Thune’s open and pragmatic approach has been key in reconciling with Trump. “His ability to be open has been helpful in getting on better terms with President Trump,” says Hager.
Thune, who gained national attention with a Senate victory over Democrat Tom Daschle over 20 years ago, has shown a knack for adapting to political shifts. South Dakota Republican Mike Rounds highlights Thune’s appeal to Trump, emphasizing their shared long-term interests for the country.
The collaboration between Thune and Trump has resulted in significant policy achievements, including tax cuts and economic growth initiatives. Thune’s efforts have also facilitated the confirmation of many of Trump’s nominees, paving the way for the recent Senate passage of the megabill.
Senate Majority Whip John Barrasso attests to the close working relationship between Trump and Thune. “We work closely together, and, of course, from the standpoint of the whip, they’re both key members of the whip team,” he says.
Thune’s efforts also involved persuading Senate holdouts, such as Lisa Murkowski of Alaska, to support the GOP’s agenda. Thune told NPR, “We’re both headed to the same destination right now… there’s an alignment of incentives, and we’ve got reasons to work together, and it’s working well.”
As Thune continues to navigate the complexities of his alliance with Trump, the effectiveness of their partnership will determine the extent to which a deeply divided party can achieve its goals.
