Once vetted there is almost zero chance of a conviction and NO WAY it doesn't get appealed if it did. The professionals in the DOJ will have to face a highly paid highly motivated equally talented defense team.
Best case scenario, in my opinion, the January 6 committee should take what they believe is the win in presenting their case to the public, without benefit of it being questioned, and call it a day. These hearings only emboldened Trump and his supporters. They're having the exact opposite effect. Those who hate trump already convicted him. Those who love him see this as more justification of a plot to get him.
The rest of us take the kids to practice, mow our lawns and try to have a healthy dinner ready.
