Republicans in Florida say Weatherford is a rare political talent with cross-party appeal who would have been a formidable candidate both in the GOP primary and in the general election. Weatherford has garnered comparisons to Rubio, having become Florida Speaker of the House at the age of 32. He left office in 2014 to form a venture capital firm with his brothers and raise his young family. Over the weekend, Florida Chief Financial Officer Jeff Atwater, who had been galvanizing support among establishment Republicans in the state, shocked political watchers by taking a pass. Attorney General Pam Bondi said last week she’d seek reelection instead of running for Senate. But the field of potential GOP candidates is still large.
