President Donald Trump pulled into a statistical tie with Democratic rival Joe Biden in Florida, one of the election’s most important battlegrounds, but Biden’s lead appeared to widen in Arizona, Reuters/Ipsos opinion polls showed on Wednesday. A separate Reuters/Ipsos national poll found that Biden also leads Trump among all U.S. likely voters by 10 percentage points. The Oct. 9-13 poll showed that 51% of likely voters were supporting Biden, while 41% were backing Trump.
