This is pretty hard to believe that an MSM poll has Trump +10. These are the same polls that showed him -15 to Hillary and -10 to pedo Pres. which of course turned out to be blatant election interference / propaganda. So if they’re showing Trump +10 it’s either extremely dire for Biden or they’re working for the deep state putting this out there to try to get Biden to resign.
I don't think they want Biden to resign - not with Kamala in the on deck circle. I think they'll continue to prop him up, let him finish his current term, but not seek reelection. This could all change, however, if he has some type of meltdown during a public appearance that's just too outrageous to ignore.
