Tom Steyer, a billionaire, is spending large amounts of money in the midterms, with some reports indicating he has spent $132 million of his own money in a gubernatorial campaign. However, it is unclear if he is still actively running for governor, as one report states he has ended his presidential bid, and another mentions other billionaires rallying behind a different candidate, Matt Mahan. The large spending in the California governor's race is attracting attention, with various donors and groups, including a PAC launched by PG&E, also investing significant amounts.
