So, in essence, there is no visible evidence because the media won't allow anyone to see the evidence?
How is that distinguishable from the "Kraken" lawsuits? In the end, their argument boiled down to the idea that the lack of evidence was itself evidence of suppression of evidence. Little wonder that when pressed and facing real-world consequences, they've admitted that they made it all up.
I've watched Biden speak in person and on TV, and while he's not, as a septugenarian, as quick witted or glib as a 30 y/o car salesman, I have zero concerns about his ability to form a sentence nor use reason and logic to reach a conclusion, nor his ability to farm out issues to competent members of his administration.
As far as the options, sadly, Joe Biden was the only D moderate and mellow enough to take on Trump. Bernie or Warren would have scared off the middle-road folks.
