Key undecided voters have moved toward Trump post-debate

June 28 (Reuters) - A group of U.S. voters who were unable to choose between and before Thursday's presidential debate delivered their verdicts after the contest and it was almost universally bad news for Biden. Of the 13 "undecideds" who spoke to Reuters, 10 described the 81-year-old Democratic president's performance against Republican candidate Trump collectively as feeble, befuddled, embarrassing and difficult to watch. Gina Gannon, 65, a retiree in the battleground state of Georgia, voted for Trump in 2016 before ditching him for Biden in 2020. "Joe Biden looked very weak and confused right from the start. It concerns me that our global enemies see Joe Biden in this manner. I was shocked and dismayed. I hate to see our president acting that way on TV and in front of the world," Gannon said. She added: "I am absolutely voting for Donald Trump now." Presidential debates typically have limited influence on voters, but Biden and Trump are in a tight race and the election will likely be decided by just thousands of votes in a handful of swing states. Both candidates need to win over the relatively small number of voters who have not yet decided who to vote for.
