As Republican lawmakers issued their condolences to Sheldon Adelson’s family following the billionaire casino mogul’s death at 87, many in the fundraising world were already asking how it might affect future GOP campaigns.

Those who work in consulting and fundraising for Republican candidates have long whispered about the day Adelson, who has donated hundreds of millions of dollars to conservative candidates and causes over the years, would finally pass. In 2020 alone, Adelson and his wife, Miriam Adelson, gave $172.7 million to GOP-related causes, including tens of millions to the efforts to reelect President Trump.
