They can impeach Biden all they'd like, but with the D's controlling the Senate it will just be a waste of time.
The big worry, for me, right now, one of them, is the process of raising the debt ceiling. The conservative R's seem so stupid that they don't know it's for money already spent and claim it means they need to cut the budget.
Meanwhile, if the debt ceiling isn't raised, the US economy goes into default and it will not be a pretty sight.
