In a way, I do agree with many of Joe Biden's detractors...he seems not to be at the top of his game. Joe Biden does seem to be elderly...and acts it. He is 6 years younger than I, and I walk and function much more gracefully than he. I grant that.
And I will also grant that it bothers me that he is not as young and spry as I would like to see our president be.
But I voted for him and do not regret that vote in any way, because he clearly was (and is) the better choice over Trump.
As I see it, right now, even with the defects I see in him, he clearly is a MUCH, MUCH better choice than Trump, DeSantis, or any of the other contenders for the Republican nomination. If Joe Biden is the Democratic Party nominee, I will definitely vote for him again rather than anyone the Republican's nominate.
So complain all you want. If the Republicans had not turned themselves into the moral shit-heap they now are, maybe this would not be happening.
