Vice President JD Vance took center stage at the Republican midterm convention in Dallas, effectively launching his unofficial 2028 presidential campaign. His keynote address on Thursday night, just before President Donald Trump's closing remarks, was seen as a crucial test of his leadership within a post-Trump Republican Party. Vance, 42, is widely considered a frontrunner to carry forward the party's populist agenda, appealing to the movement's core activists due to his youth and policy positions, including support for domestic manufacturing, restrictive immigration, and a less interventionist foreign policy.

The convention, dubbed "Trumpapalooza" by some, heavily featured President Trump, 80, who is constitutionally barred from seeking a third term. Trump, despite low approval ratings, aimed to mobilize his base and made an extraordinary proposal to pay every U.S. adult a $5,000 "Trump dividend" if Republicans win the November 3 congressional elections, a plan estimated to cost over $1 trillion. Vance's speech offered clues on how he might shape the party, as Trump has reportedly gauged opinions on whether Vance or Secretary of State Marco Rubio is the preferred successor.

Vance’s appearance was marked by chants of "JD, JD, JD" from delegates and he raised $2 million for the Republican National Committee at a Dallas fundraiser. Excerpts from his speech highlighted themes important to the Republican base, including family values and protection against "radical" ideologies, clean water, and ensuring fair competition for daughters in sports. The convention also served to showcase other potential presidential hopefuls like Senator Ted Cruz, who emphasized the ongoing debate over the party's future direction beyond Vance and Rubio.

The broader context of the convention was the Republican Party's effort to avoid midterm losses and protect their House and Senate majorities, despite historical headwinds against the sitting president's party and concerns about the economy and the war with Iran. Democrats, in counter-programming, criticized the convention as an "opulent spectacle" out of touch with average American families, pointing to the economic struggles faced by many.
