At a rally a few days ago, Trump said this:
"After just five months the Biden administration is already a complete and total catastrophe. Crime is surging, murders are soaring, police departments are being gutted, illegal aliens are overrunning our borders. Joe Biden is destroying our nation right before our very own eyes."
Apart from the typical Trump hyperbole ('a complete and total catastrophe'), it's very hard to disagree with the points he made.
Yes, crime and murders are rising and illegal immigrants are crossing the border, not to mention issues with the police.
Trump will probably be back in politics in some form or another, even if it's just as an adviser to a Republican candidate.
