RNC Opens First-Ever Midterm Convention in Dallas Today as Trump Promises a 'Surprise' and Iran Tensions Simmer

The Republican National Committee's first-ever midterm national convention opens today, Wednesday, September 9, at Dallas' American Airlines Center, running through Thursday, September 10, with 55 days left until Election Day.

Democrats held similar midterm gatherings in the 1970s and 1980s. This is the RNC's first attempt at one, and organizers are betting big: roughly 20,000 attendees are expected, making it the party's largest convention in a decade, according to CBS News. For the first time, the RNC has opened a convention to ordinary Americans, distributing free tickets through a lottery, according to the Daily Wire.

President Trump will deliver the keynote address tonight and closing remarks Thursday. Vice President JD Vance keynotes the second night. The Daily Wire reported, citing a GOP source, that Trump is expected to unveil a "surprise announcement" during his Thursday closing remarks. No further detail on its content has been made public.

More than 100 speakers and panels are scheduled, according to the RNC, touching tax policy, healthcare, election integrity, border security, education and parental rights, and trade. Thursday's program includes a segment honoring Charlie Kirk around the anniversary of his assassination, along with a 9/11 remembrance.

Cabinet officials headlining include Treasury Secretary Scott Bessent, Deputy Attorney General Todd Blanche, Health and Human Services Secretary Robert F. Kennedy Jr., Medicare and Medicaid Administrator Dr. Mehmet Oz, and HUD Secretary Scott Turner, alongside White House Press Secretary Karoline Leavitt and Donald Trump Jr. Congressional leadership on the roster includes House Speaker Mike Johnson, Senate Majority Whip John Barrasso, NRSC Chairman Tim Scott, House Majority Leader Steve Scalise and RNC Chairman Joe Gruters, according to the Daily Signal. Senate Majority Leader John Thune plans to attend but is not listed among the speakers, per the Epoch Times.

Not every Republican is showing up. Rep. Ralph Norman (R-S.C.), who lost a special Senate primary to Trump-backed Sen. Lindsey Graham, told reporters he's skipping it: "I've been campaigning for a year and a half." Johnson told reporters attendance isn't mandatory, noting lawmakers have "got to all make their own individual decision" with early voting approaching nationwide.

Texas Is More Than the Host State

Gov. Greg Abbott, Sen. Ted Cruz and Texas Attorney General Ken Paxton will use the Dallas stage to shore up one of the country's most closely watched Senate races. Paxton, Trump's endorsed nominee, faces Democratic state Rep. James Talarico. VoteHub's polling average, working with the CBS News Data Desk, has Talarico ahead by 2.4 points, though the broader model still calls the race a toss-up because some undecided voters have backed Republicans before.

Nationally, the RealClearPolitics generic congressional ballot average gives Democrats a roughly 5.8-point edge, according to the Daily Wire. History isn't on the White House party's side in midterms generally, and Republicans are trying to counter that with turnout mechanics rather than just messaging.

Not every conservative voice is convinced the strategy addresses the real risk. Chris McNutt, president of Texas Gun Rights, told the Epoch Times: "We believe Republicans are walking into a bloodbath because they are taking so many Republican constituencies, like gun owners, for granted." That's a specific warning from inside the coalition the convention is trying to energize, not an outside attack, and it names a concrete grievance rather than a vague one.

On the other side, RNC spokeswoman Natalie Baldassarre pushed back on any suggestion Republicans lack a record to run on, telling the Daily Wire the party has delivered "historic tax relief and lower prescription drug prices," support for farmers and rural hospitals, while "Democrats remain divided and distracted."

Iran Looms Over the Room

The convention opens as Washington escalates pressure on Tehran diplomatically. The U.S. is preparing a UN Security Council referral and a resolution demanding Iran "urgently remedy its non-compliance" and restore IAEA inspection access, according to Bloomberg's reporting cited by Fox News. IAEA Director General Rafael Grossi said inspectors have neither received information on Iran's nuclear material nor been granted facility access. Iranian Foreign Ministry spokesman Esmail Baghaei called European backers of the resolution "irrational" and warned of retaliation.

A senior U.S. official told Al Jazeera, as reported by Breitbart, that the Strait of Hormuz is "fully open and under U.S. Navy control" following a months-long mine-clearing operation, with roughly 20 U.S. warships enforcing a blockade of Iranian ports reimposed in mid-July. U.S. Central Command said it has redirected 94 commercial vessels, disabled three and boarded two since then. Iran's Supreme National Security Council chief Mohsen Rezaei countered by announcing a new maritime "exclusion zone," saying the "operational posture toward U.S. warships and bases has been fundamentally recalibrated."

Trump has tied the conflict directly to gas prices, predicting on Truth Social that prices will fall to "Three Dollars a gallon" and eventually "below Two Dollars a gallon" once the war ends. CBS News reported that elevated gas prices and the ongoing conflict are shaping voter concerns ahead of November, alongside affordability and immigration enforcement, issues Democrats are using to offer a different assessment of the administration's record.

What Trump's Thursday "surprise announcement" contains, and whether the convention moves the Texas Senate race or the national generic-ballot gap, will start to show up in polling and fundraising numbers over the coming weeks.
