Sorry - I disagree. It sounds exactly the opposite - Trump fears Biden more than he does any possible incoming newcomer who has no experienced team behind him/her, no campaign funds in order to run, and no record like the past three and a half years that Biden does. Theres been an awful lot of silence from Trump himself since the debate - compared to the flow of nonsense he usually spews. Now he wants another debate without monitors - without the non-existent "rules" from the last debate. Just an opportunity to do the gishing he did in the debate only without brakes.
You have your opinion and I have mine about this. There are people with more experience & research abilities than myself that feel the way I do. Possibly not a fan of Bidens, but thinking he is the safer course going against Trump.
