I think it was a mistake to not call witnesses, but not for the reason many say. I think calling witnesses would have led to an extended delay during which ultimately the Senate would have returned to pressing business (e.g. COVID relief) while the managers would have had months to collect data from witnesses. Every day new information comes out that leads closer and closer to Trump's inner circle. That said, the managers did a great job with what they had to work with and it was the most bipartisan vote for conviction ever.
