The great Justice Oliver Wendell Holmes defined the role of lawyers as predicting, in fact, what the courts will decide. So here is an objective and independent prediction as to how the courts will likely resolve the number of challenges brought by Trump and his lawyers.
He could win his case in Pennsylvania about ballots mailed before the end of the election but received over the next three days. Justice Samuel Alito, who oversees the federal circuit that includes Pennsylvania, has signalled Supreme Court interest in that issue by ordering all of these ballots to be counted separately then segregated.
The Pennsylvania secretary of state was doing this, but the order from Alito made clear that there are at least some others who could be ready to discount those votes.
Article Two provides that state legislatures determine rules for selecting members of the Electoral College. But it was the Pennsylvania high court, not the legislature, that extended time for receiving and counting mailed ballots by three days. It may have been a sensible decision in light of the coronavirus and problems with delivery. According to lawyers for Trump, the state high court lacked the authority to change the rules that mailed ballots have to be received before the end of the election.
Twenty years ago, in the Supreme Court decision in George Bush versus Al Gore, the majority voted along strictly partisan lines to stop the count ordered by the Florida high court. That decision had been based in part on Article Two. It is likely, therefore, that the even more partisan current Supreme Court might well side with Trump over this issue.
This is not clear cut folks, you may like it done and dusted and 'all lies' but it is not that simple.
Those that do not seem to understand the need for discussion and at the very least, consider different views are really wishing to live in a vast echo chamber and they will be surprised when events turn out differently to how they imagine/expect (Brexit and Trump's first win as two examples) Come out of the echo chamber, consider the two sides and try to expand your thinking. By only seeing one side (Biden for instance) you are underestimating the power of the other side. I am offering a different view, not because I am a Republican, because I am not, but because it is important for balance. Particularly on threads like this, that become very blinkered.
An ability (or lack of) to think beyond your own political view and consider other points is startling on this thread.
