Some of America’s wealthiest political donors poured hundreds of millions of dollars into Tuesday’s midterm elections, only to watch several heavily-financed candidates lose as Democrats captured control of Congress.
The election followed a surge in political contributions from wealthy donors, enabled by decades of court decisions loosening campaign finance restrictions. Despite the enormous spending, several high-profile Republican candidates suffered defeats, raising questions about how much electoral success even the wealthiest political backers can buy.
The 40 largest political donors contributed more than $2.4 billion through mid-October, according to an analysis by the Brennan Center for Justice. That figure exceeded the inflation-adjusted contributions from the 40 largest donors during the entire 2022 midterm election cycle by more than 50%.
Tesla and SpaceX CEO Elon Musk emerged as one of the election’s most prominent financial backers, contributing approximately $446 million to political organizations as of late October, according to Federal Election Commission (FEC) data analyzed by The Washington Post.
Musk’s contributions included substantial support for Republican political organizations seeking to maintain control of Congress, including the Senate Leadership Fund, Congressional Leadership Fund and America PAC.
One of the most notable Republican defeats came in Texas, where Democrat state Rep. James Talarico defeated Republican Attorney General Ken Paxton in a Senate race that attracted substantial spending from Musk. The billionaire reportedly poured more than $150 million into the contest, but Paxton lost by a wide-margin, according to election returns.
Other wealthy donors poured enormous sums into the election cycle.
Shipping supply magnates Richard and Elizabeth Uihlein contributed approximately $150 million to Republican-aligned political organizations, including roughly $136.7 million to Restoration of America, according to a Washington Post analysis. Their contributions included support for Wisconsin Republican congressional candidate Jessi Ebben, who lost the August Republican primary for the state’s 7th Congressional District to Michael Alfonso.
Financier Jeff Yass and his wife, Janine, contributed approximately $110 million to Republican-aligned political efforts, including $30 million to V-Pac: Victors, Not Victims, which supported Republican Vivek Ramaswamy’s failed gubernatorial campaign in Ohio. Ramaswamy lost Tuesday to Democrat Amy Acton, who received approximately 52% of the vote compared with Ramaswamy’s 44%, according to election returns.
