Correction: the only viable opponent party ran the wrong person and chose the wrong strategy to oppose him. Their candidate(s) weren't the "right person" to be president. And despite a year of Trump, that opponent party is still unpopular.
It's a testament to how broken the system is. They'll all acting stupidly, and no one is the good guys.
> If impeachment and conviction aren’t on the table, then the least our leaders—Republicans and Democrats alike—must do is stand together and speak with one clear, unmistakable voice in opposition.
Wake up, you're dreaming.
What needs to happen is the Democrats need to listen to their own rhetoric and actually take the threat seriously, instead of seeing an opportunity to win a narrow partisan victory for their extremists. They need to reconfigure into a truly majoritarian party, which will make the progressives unhappy, so it won't happen.
> Our credibility with Europe, already strained, will continue to erode if the world sees that American leadership is unwilling or unable to check reckless behavior.
Honestly, few care about our "credibility with Europe." And they've got too many of their own problems to be considered in such a superior position.
