Trump says he wants to stop the counts, but we’ll see if he does anything. Trump says a lot of things. The Texas court case where both State and Federal courts refused to invalidate over 100,000 legal votes gives me hope that the Supreme Court will not rubber-stamp any demand Trump makes (even if some of the Justices would do that).
Trump is a massive blowhard. He could potentially turn this into a fight just to save face. I wouldn't put it past him.
Incidentally, as a sidebar: every pollster that was predicting the election results needs to be fired. I don't think I have seen any situation were the polls were so utterly wrong. I don't know if it was stupidity or bias. Maybe a bit of both. Even Nate Silver, who is supposed to be one of the smart ones, had Biden at 90% chance of winning and Trump at 10%. While the actual ratio turned out to be about 50/50.
