This is some dumb fan fiction. Sure, could this happen... yes... but it's an obscene long shot and would require a set of conditions to even have it happen. I think it's pretty low for Newsweek to publish this crap.
Here are the key elements that need to occur:
1) The election is kind of close, but Biden wins. Certainly possible.
2) Trump disputes the election. Fucking, duh.
3) He evokes emergency powers to"investigate foreign influence". There is no particular reason why he couldn't do this.
4) Four Republican controlled swing states refuse to ratify election results.
5) The Supreme Court doesn't really get involved, and just says the EC must occur on December 14th.
6) The election gets kicked down to Congress, where there are 26 Republican delegations, 23 Democratic, and 1 tie. Republicans carry it.
None of this is "obscene". The biggest thing (steps 4, and 6) is seeing if all Republicans will truly and absolutely slide their own country into undeniable fascism, but frankly, I've seen nothing in these four years to indicate that they'll suddenly grow a conscience.
I still view it as a low probability, but I think it's definitely in the realm of possibility.
