It certainly won’t happen if we sit back and say it won’t.
I fully appreciate what you’re saying (i.e., we shouldn’t give up on the possibility of removing him from office). However, in view of the nature of this “historic presidency”, its relatively short time horizon, and the Republican fear factor, I just don’t see impeachment in the cards under any circumstances. More likely that an agreement would be struck to push him aside for the remainder of his presidency.
Just my humble opinion and I would be overjoyed to be proven wrong.
