The biggest financial backer of Gov. Ron DeSantis’ presidential ambitions won’t provide more money — unless the candidate moderates some of his policies and manages to convince more big financial backers that he’s viable. Robert Bigelow, a Las Vegas billionaire, contributed $20 million on March 30 to the super PAC supporting DeSantis’ campaign for the Republican presidential nomination — two-fifths of the $48.1 million the organization raised in its first five months of existence. In 2022, Bigelow gave $10 million to DeSantis’ previous state political action committee.
