Approximately 100 of the United States' 705 billionaires have donated to candidates seeking the Democratic presidential nomination, an analysis of the Federal Election Commission database by Forbes found. The list of donors is remarkably similar to Business Insider's list of the largest political donors of 2018, suggesting that America's biggest donors are a static group of individuals. California Senator Kamala Harris seems to be billionaires' favorite liberal candidate, as 46 of them have donated to her campaign in 2019 thus far, according to Forbes.
