There are two things I see as necessary for an intervention. First, that President Trump himself is in such a place where he realizes that all his efforts have come to naught, and that only God can save the election, and indeed the nation. This is a process of humbling.
I disagree. Although that is a desirable outcome, both history and scripture show otherwise. God can deliver a nation by type of leader, provided the people humble themselves and cry out to the Lord.
You are not electing a pastor, but a president, and sadly, most pastor type characters would be useless in that role.
God anointed Cyrus to liberate the Jews, hardly the best example of perfection.
Probably the most important single change in English history, came about via Henry 8th. He wanted a divorce, which was forbidden under the Catholic Church.
He was a proud man and never really changed his arrogant nature, nevertheless he set in motion a spiritual freedom that revolutionised and transformed England.
Under the council of the Archbishop of Canterbury, Cranmer, Henry declared the complete separation of England from Rome. He made himself head of the church, instead of the Pope.
The new Church of England was still Catholic in practice, but it laid the foundation for a spiritual revolution to take place in due time.
Having said that, don't get me wrong, I believe that the Lord has been working deeply on Trump, and when this election fraud is overturned, I believe we will see Trump fully acknowledging that it is God who has done it, not him.
