Could Hurricane Milton stop Trump winning the election?

Nearly every modern US presidential election cycle has been upended by an unforeseen 'surprise' of one sort or another.

In July 1972, Democratic presidential candidate George McGovern was shocked to learn, after his party's summer convention, that his running mate Thomas Eagleton had secretly received electroshock therapy to treat bouts of depression.

That was enough to discredit Eagleton with the grand poohbahs of the Democratic Party and help doom McGovern's campaign.
