From the jump, the battle for the Republican U.S. Senate nomination has featured a massive cash imbalance, with incumbent U.S. Sen. John Cornyn and his allies in Senate GOP leadership unleashing millions in ads to pull him to a first-place finish in the March primary over Attorney General Ken Paxton.
That financial disparity has persisted in the runoff after neither Cornyn nor Paxton broke 50% of the vote in round one.
Through Wednesday, pro-Cornyn forces had outspent the Paxton side more than four to one, according to media tracking firm AdImpact, allowing the incumbent senator's allies to dominate the airwaves with ads attacking Paxton, a warrior of the far right, as incompetent, corrupt and adulterous.
