Biden's competence as President...he gets asked challenging questions...doesn't get flustered...has no external assistance of any kind...all on his own...every word being judged...fully understands the questions and their implications...delivers a cogent response every time...delivers a clear message on what U.S. policy is...now and for the future...moreover, Biden was able to interject a bit of humor and was respectful of each and every reporter who confronted him, which to me shows confidence and leadership.
Watch the video and tell me where he failed...or where he was "clueless"...or where he was "senile"...get specific, instead of making vague insinuations...
...and if you can handle more than one thought at a time, consider that real progress is being made both domestically and internationally...with a fair part of it getting bi-partisan approval...I'm not sure what you're really looking for.
