the media is owned by the same people that want him out and they will be raising Joe's fake poll numbers
If they are fake-raising those numbers, this will probably result in the exact opposite of what they want to achieve
If Biden leads the polls, you have a) some undecided, but likely democratic, voters not giving their vote, because polls say Biden will win anyway and b) this will motivate the undecided, but likely republican, voters to actually participate. I really believe that Biden doesn't have a chance against Trump.
Agree. Biden looks very fragile to me, which is of course not unusual for a person of his age; he often seems a bit clumsy and is not very good at defending himself. But he also lacks leadership, personality, charisma. The political/bias aspects aside, Trump is a good leader and has personality - whether you like his leadership/personality is another story.
