I am always careful of anything I see on Twitter... the video presented by whoever that twitter person is, has been heavily doctored and edited. Pieced together etc.
Here is the full, unedited video:
Having said that... in the unedited video he didn't do a helluva lot better. He pretty consistently lost his train of thought and was all over the place in his answers because of that. And yes, pretty obvious, especially Joy Behar, was "assisting" him and cutting off his "uh...um...uh..." before it got too bad.
So the point is the same. But we don't need to engage in the same tactics the left does to show Biden's issues.
* Note - not saying the OP is guilty of this, he didn't create the video. I am just way careful of everything Twitter.
