4-4 decision over what exactly? To allow states to
stop counting ballots because of massive turnout? To disallow it? I'd hope a 4-4 gridlock in some cases stops party shenanigans or at least does not lend legitimacy to any attempts to prematurely stop the count.
The funny thing is it's beginning to look like a
landslide. If it were close, requiring recounts like in 2000, there might be a last-minute need for SCOTUS. Trump seems to be gearing up to bring the courts in early though, to stop even the
first round of counting if it looks like he's going to lose.
So yeah in the scenario Trump is imagining, I think no decision would be better than the wrong one.
The simple fact is rushing to get a court pick in just before an election whose results he fully intends to contest is leaning on the scales a little too heavily. And having a candidate for a justice coming in knowing that and refusing to say whether or not she'll play along is an indication he's picking the right person to do that particular job.
