“Sleepy Joe” Biden versus “Trumpety” Trump

Too close to call? Who says? The main stream media? (It looks like the perfect way to keep people glued to their televisions and internet devices: more advertising revenue.)
If I’d been a betting man (which I’m not, anymore), I would have put money on Trump to win it outright. And Trump, thinking positive thoughts, would agree with me.
But that’s not what ‘the powers that be’ want as the result, so we’ll be kept in limbo until every avenue of legal and political moves are navigated by each side of the Red/Blue divide.
And that’s where my question comes in: because there are 538 Electoral College votes (ECV) up for grabs, it could conceivably come down to a tie of 269 votes each.
Who then casts the deciding vote?
And please don’t say the United States Supreme Court, because that has been stacked in Trump’s favour, and wouldn’t be fair to Biden.
A more fair way would be to give the presidency to the individual who garnered the most popular votes.
As of now, that would be Biden, by almost 3 million votes, wouldn’t it?
(Haven’t we seen this scenario before?)
So, we shall see what happens next.
