The Republican National Committee is preparing to welcome roughly 20,000 people to Dallas for its first-ever midterm convention, a two-day gathering designed to energize Republican voters and build momentum heading into the November elections.

The convention is scheduled for Sept. 9-10 at the American Airlines Center and will feature President Donald Trump and Vice President JD Vance, along with other top Republican leaders and candidates. Organizers have described the event as an opportunity to celebrate the Republican Party’s accomplishments, showcase its candidates and unite supporters behind an America First agenda.

At least 45 Republicans surveyed by Politico have said they will not attend, while more than 20 others are still weighing whether to participate. Several Republicans cited scheduling conflicts, fundraisers and responsibilities in their home districts. Others raised concerns about the suggested $25,000 minimum contribution associated with attending.

Rep. Tom Barrett, R-Mich., said he believed he would be more useful remaining in his district and spending time with constituents and his family.

One anonymous House Republican described the convention as a “waste of time” and argued that Republicans should focus more heavily on persuading independent voters rather than rallying their existing base.

Despite those concerns, the expected overall attendance is substantial. The National Republican Congressional Committee has distributed more than 2,000 tickets, while roughly 100 Republican members and candidates have reportedly confirmed their participation. A public ticket lottery has also been offered, allowing ordinary Republican supporters to attend the historic gathering.

Trump is scheduled to appear both nights, while Vance will deliver the keynote address Wednesday. House Speaker Mike Johnson, R-La., and Senate Majority Leader John Thune, R-S.D., are also expected to attend. Candidates facing competitive Senate races, including former Rep. Mike Rogers of Michigan and Sen. Jon Husted of Ohio, are among those planning to participate.

Johnson said members must make their own decisions but defended the gathering as an important event for the party.

RNC national press secretary Natalie Baldassarre said enthusiasm for the convention has been “incredible,” arguing that Republicans are rallying around Trump’s America First agenda and that the event will help build momentum heading into November.

The convention will come at a critical point in the 2026 election cycle as Republicans work to defend their congressional majorities. With control of both the House and Senate at stake, the Dallas gathering is expected to serve as a major opportunity for Republican activists, voters, candidates, and party leaders to rally together before Election Day.
