Wealthy candidates who self-fund their campaigns for Congress and state offices have generally faced mixed outcomes, with a majority failing to secure victory despite significant personal spending. Recent elections underscore the challenges that even well-financed contenders encounter when seeking public office.
Most notably, in Maryland’s recent Democratic primary on June 23, billionaire and former Congressman David Trone’s $25 million bid to return to the House ended in defeat. Trone, who co-founded a national alcohol retailer and has been one of the highest self-funders in congressional history, has spent over $134 million across six campaigns during the past decade. While he won three terms in the House, he has also expended more than $101 million on unsuccessful races. His latest attempt to reclaim a seat yielded a loss to incumbent Rep. April McClain Delaney, who, while investing over $7 million of her own money, spent less than half of Trone’s campaign outlay.
Trone’s setback reflects a broader trend among high-spending self-funders. An analysis of campaign finance data since 2000 shows that among the top 20 self-funded congressional campaigns by expenditure, only four candidates have won. Combined, those campaigns saw candidates spend over $600 million.
Other prominent self-funded candidates have also experienced varied results. In California, billionaire climate activist Tom Steyer spent $218 million in the 2026 Democratic gubernatorial primary but failed to advance to the general election. Similarly, Mehmet Oz, a television personality endorsed by former President Donald Trump, lost his 2022 Senate race in Pennsylvania despite vigorous spending.
Successful self-funders tend to have either prior political experience or strong name recognition. Rick Scott, the former Florida governor, spent approximately $63 million to narrowly defeat Democratic incumbent Bill Nelson in the 2018 U.S. Senate race. He repeated a win in his 2024 re-election bid, outspending Democratic challenger Debbie Mucarsel-Powell. In New Jersey, Jon S. Corzine, a former Goldman Sachs CEO, spent $60 million in 2000 to win a Senate seat, setting a then-record for self-funded spending.
On the other hand, some well-financed candidates have repeatedly fallen short. Linda McMahon, former head of World Wrestling Entertainment and current U.S. Education Secretary, invested heavily in two Senate campaigns in Connecticut—$50 million in 2010 and $48 million in 2012—only to lose both to Democratic opponents. Bob Hugin, ex-chairman of pharmaceutical company Celgene, spent $36 million in his 2018 Senate race in New Jersey but was defeated by incumbent Democrat Bob Menendez. Businessman Blair Hull’s $28 million bid in the 2004 Illinois Senate primary ended in a third-place finish behind Barack Obama.
As these examples illustrate, substantial personal wealth and spending power do not guarantee electoral success. Institutional support, voter preferences, and other local political dynamics continue to play critical roles in determining the outcome of races, even when candidates pour tens of millions of their own money into campaigns.
