Speaker Paul Ryan (R-Wis.) said Thursday there’s no chance he’ll emerge as the GOP presidential nominee if no candidate captures enough delegates before this summer’s convention. For the first time, however, Ryan acknowledged the increasing likelihood that the GOP nominee will be decided in Cleveland at what’s known as a contested or open convention. The Speaker’s comments Thursday suggest party leaders are beginning to prepare for a floor fight at the convention at Quicken Loans Arena in downtown Cleveland. When The Hill asked him in January about a possible contested convention, Ryan dismissed the idea. “I think it’s ridiculous to talk about it,” he said at the GOP retreat in Baltimore.
