Ken Paxton, a Republican from Texas, and Graham Platner, a Democrat from Maine, visited Washington on June 2, 2026, to gain support for their Senate campaigns. Paxton's itinerary included a White House visit, while both aimed to strengthen their positions within their respective parties.

Texas Attorney General Ken Paxton has unseated incumbent Senator John Cornyn in a historic Republican primary runoff, marking one of the most expensive Senate races in U.S. history with over $160 million spent. The May 28, 2026 victory, fueled by former President Donald Trump's endorsement, saw Paxton secure 63.8% of votes against Cornyn's 36.2% with two-thirds of ballots counted. The outcome solidifies Trump's influence in GOP politics while creating new opportunities for Democrats, who will field rising star James Talarico against the scandal-plagued Paxton in November. The race also highlighted shifting voter demographics, with Hispanic voters showing increased Democratic leanings. The New York Times+4

🗳️ Trump's Decisive Endorsement

Trump's vocal support for Paxton, whom he called a "true MAGA Warrior," proved pivotal in the runoff. The endorsement surprised many given Cornyn's attempts to align with Trump, including reversing his stance on the filibuster. Exit polls showed 72% of Paxton voters cited Trump's backing as their primary motivation. The former president framed the race as a loyalty test, criticizing Cornyn for insufficient support during his administration. Paxton celebrated the win at a Plano watch party, calling Trump's endorsement the "most powerful force in politics." The New York Times+2

🏛️ GOP Fractures Exposed

The bitter campaign revealed deepening rifts within the Republican Party. While Paxton's victory demonstrates Trump's continued sway over the base, establishment Republicans fear his scandals could jeopardize the traditionally safe Texas seat. Cornyn conceded but pledged party unity, while some GOP strategists privately expressed concerns about holding the seat in November. The race saw record-breaking spending as both factions battled for control, with Democrats viewing the divisive primary as an opening to flip the seat. The Guardian+2

📊 Historic Campaign Spending

The runoff shattered spending records with $160+ million allocated primarily to advertising blitzes. Key financial aspects:

Category	Paxton Campaign	Cornyn Campaign
TV Ads	$58M	$62M
Digital	$22M	$18M
Field Operations	$15M	$20M
Paxton's late surge was fueled by a $12M ad buy in final weeks contrasting his Trump endorsement with Cornyn's perceived wavering loyalty. The New York Times+2

🗣️ Scandal vs. Experience Debate

The campaign became a referendum on Paxton's legal troubles versus Cornyn's 24-year Senate tenure. Democrats immediately seized on Paxton's vulnerabilities, with Talarico's campaign releasing a statement calling the nominee "ethically unfit." Republican operatives acknowledge the general election will test whether Texas voters prioritize party loyalty over character concerns, as Talarico gains traction with a populist message.
