Ken Paxton’s surprise primary win over Senator John Cornyn in Texas has alarmed Republican strategists and donors, who fear the ensuing general election could demand unprecedented financial resources.

Analysts and GOP insiders told Politico that defending the Texas seat could require up to $150 million, money that might otherwise support competitive races in states like Maine, Michigan, Ohio, and North Carolina.Cornyn, a seasoned fundraiser, typically relied on his extensive donor network, whereas Paxton entered the runoff with only $2.3 million.

Trump's last-minute endorsement of Paxton has intensified concerns, as strategists warn the party may face a 'horror movie' scenario if Paxton struggles to appeal beyond MAGA voters.

Democratic challenger James Talarico, by contrast, quickly raised $600,000 in two hours following Paxton's victory, signaling a potentially expensive race.Overall spending in the Texas Senate contest could surpass $550 million, more than double the $210 million spent in 2024.

Complicating matters for Republicans, Trump's low approval ratings, rising gas prices, and an unpopular war in Iran make it difficult to play defense in a state they had expected to hold comfortably.The race underscores the growing tension within the GOP between establishment priorities and the influence of Trump-backed candidates.
