Jeb Bush's largest donor has decided to run full-page ads targeting Donald Trump that call the GOP presidential hopeful "a narcissistic BULLYionaire." Billionaire Mike Fernandez, who has contributed $3 million to Right to Rise, the main super-PAC supporting Bush's presidential bid, announced his decision on Friday after a poll showed Trump leading the GOP field with 36 percent support. Bush trails, with just 3 percent.
