Senate Majority Leader John Thune has issued a stark warning that Republicans could lose control of the Senate in the upcoming November elections, a more cautious assessment than that offered by House Speaker Mike Johnson.

'I worry about that, for sure,' Thune stated in an interview with KELO-TV, acknowledging that the Republican party's hold on the Senate is no longer secure. 'I'm a realist, and I just think you — I don't ever try and sugarcoat things. I think it's a competitive environment right now.'

Thune's remarks stand in contrast to Speaker Johnson, who has publicly projected confidence that Republicans will retain their House majority, defying historical trends for parties in power during midterm elections.

'You can write it or quote me. I've been saying this over and over, but Republicans are going to defy history in 63 days, and we're going to hold this House majority,' Johnson told reporters. Republicans currently hold 218 seats in the House, with Democrats at 212, one independent, and four vacancies. Democrats would need a net gain of five to six seats to secure a majority.

Electoral Headwinds

Thune's warning coincides with findings from a new Daily Mail/JL Partners poll, which indicates growing voter frustration with the Trump administration on two key issues: the ongoing conflict in Iran and the cost of living. The poll reveals that more than 40 percent of voters who supported Trump in 2024 believe he is not adequately addressing inflation and the cost of living. Furthermore, 49 percent of all voters surveyed indicated that the military action against Iran was the wrong decision.

Republicans currently hold a slim 53-47 majority in the Senate. Democrats require a net gain of just four seats to gain control of the chamber. This electoral challenge is compounded by the fact that Democrats would need to flip seats in at least two states that Donald Trump carried by double digits in the 2024 presidential election.

Thune has specifically identified Texas as a critical state for Republicans to win. He stated that the party "flat have to win there" as Democratic State Representative James Talarico competes against Republican nominee Ken Paxton for a U.S. Senate seat. "All of our allies out there, including the president and his team and their resources, need to be brought to bear on Texas, because it's not one that we can lose if we're going to hang on to a Republican majority," Thune told Fox News.
