Supporters say John Fetterman was noticeably smoother at a weekend event in York, Pennsylvania. The lieutenant governor addressed lingering questions about his health by saying, “In January, I’m going to be much better and Dr. Oz will still be a fraud.” Since a stroke in May, he’s campaigned for the U.S. Senate largely on social media, but with polls showing a tighter race with Republican Dr. Mehmet Oz, he’s been hitting the campaign trail with only a month to go. Police say the crowd at the York expo Saturday totaled more than 800.
