-Source-The Roanoke Times- Razor-thin margins in Floridas bitter races for the U.S. Senate and governor are raising the specter of possible recounts potentially prolonging two of the most closely watched contests of the nations midterm elections. In the governors race Democrat Andrew Gillums campaign said Thursday its readying for a possible recount. He conceded to Republican Ron DeSantis on Tuesday night though the race has since tightened. As of Thursday afternoon DeSantis led Gillum by 0.47 percentage point. Meanwhile Democratic incumbent Sen. Bill Nelson has begun preparing for a potential recount in a race still too close to call against Republican Gov. Rick Scott. Nelsons lawyer called that race a jump ball though Scotts campaign urged Nelson to concede. Scott held a 0.21 percentage lead over Nelson on Thursday afternoon.
