The problem is that the Trump and Biden camps set the rules at this debate.
The moderators were not allowed to live fact check, nor could they cut the candidate’s mic during their allotted time.
This means that the responsibility of countering Trump’s lies fell completely on Biden. There are so many lies, it would be a difficult task for any person.
But Biden signed up for this, and he failed spectacularly. None of Trump’s bullshit was effectively countered.
Riots in the streets now is preferable to the current path where our great grandchildren all die from heat stroke.
But I agree with your point, the political calculus doesn’t make sense. If politicians are afraid of riots in the streets then we need to give them something worse to fear.
Ecoterrorism or extinction seem to be the only options available.
