Paxton’s Blowout Leaves Texas Republicans With a Riskier Senate Bet
Trump’s late endorsement pushed Ken Paxton past John Cornyn, but the win gives Democrats a more vulnerable November target and forces GOP triage.
Ken Paxton didn’t just beat John Cornyn in the Texas GOP Senate runoff; he crushed him, winning about 64 percent with more than 95 percent of the vote reported, according to 
The Hill. That result matters because Cornyn had the money, the institutional backing and the incumbency. His campaign and allied groups spent roughly $90 million on ads since last year, most of it aimed at defining Paxton as too damaged to win a general election, according to 
Associated Press. It still wasn’t enough once Donald Trump moved late and decisively behind Paxton.
Trump settled the primary — at a cost
This was the clearest possible test of Trump’s power over Republican primary voters, and he passed it. Paxton got the president’s endorsement in the final days, then turned it into a loyalty referendum: Trump’s pick won, while Cornyn became the latest GOP incumbent to be punished for insufficient devotion to the leader of the party, as Associated Press reported. Senate Republicans wanted Cornyn because they see him as the safer general-election candidate. Trump wanted Paxton because Paxton is more useful as proof that the base still follows him.
That is the power dynamic now. Trump can still make a nomination contest about allegiance, not electability, and win it. The immediate beneficiary is Paxton. The longer-term beneficiary is Trump, who keeps showing that party elites can warn about November all they want, but they do not control the primary electorate.
Texas Republicans bought a weaker November matchup
The problem for Republicans is that Paxton’s win does not settle the race; it may have tightened it. The Hill reported that Cook Political Report already shifted the Senate contest toward Democrats after the runoff, even though Republicans still start as favorites. That shift reflects the same judgment Senate leaders made when they backed Cornyn: Paxton brings liabilities that matter in a general election, especially his impeachment history, ethics baggage and personal controversies, all of which were central to the anti-Paxton barrage described by Associated Press.
Democrats now get to run against the most polarizing Republican in the field, not the most conventional one. That is why the race has suddenly become relevant to 
US Politics and to the broader Senate map. It is also why the Texas contest is now a pressure point for national Republicans: every dollar spent defending Paxton is a dollar not spent elsewhere, exactly the problem GOP strategists were warning about before the runoff, according to 
Politico.
What to watch next
The next real test is whether national Republicans keep money flowing into Texas or start treating the seat as a defensive liability. James Talarico, the Democratic nominee, already has a fundraising operation that can exploit Paxton’s weaknesses; 
The New York Times reported he raised $27 million in the first quarter, nearly four times Paxton’s total for the whole race. If that advantage holds, Democrats will try to turn Paxton into a statewide drag, not just a Senate candidate.
Also watch the rest of the Texas runoff map. The same day delivered hard-fought Democratic member-on-member fights in Houston and Dallas, a sign that Republican redistricting has reshaped the state’s politics in ways that reach beyond the Senate race, according to The Hill. The next decision point is simple: whether Republicans keep treating Texas as safely red, or start spending like they know Paxton just made it less so.
