SWANTON, Ohio – President Donald Trump was interrupted twice during an Ohio rally this week by sign-waving supporters chanting, “Fill that seat!”“I will fill that seat,” Trump responded before launching into an extended riff on his plans to quickly nominate a successor to Supreme Court Justice Ruth Bader Ginsburg. “They say it’s the most important thing a president can do.”During a swing through Wisconsin a few hours earlier, there were no big crowds for Democrat Joe Biden, whose campaign is strictly following protocols to combat the coronavirus.
