They didn't let Trump win. He's always been in control of this.
He knows about Hammer and Scorecard and how the Democrat Machine operates. He knew it would happen. He stopped them mid fraud and reversed the Hammer and Scorecard tool. Remember, he's always had their 'Playbook'
This meant that Trump won and they couldn't scream he'd cheated because they'd have to admit to the use of Hammer and Scorecard.
So they attempted to bring him down for 4 years. He knew that, Flynn telling Susan Rice China was a bigger threat than Russia and they were a declining power. Susan knew that, that's why they went after him.
So Russiagate happens, Mueller happens, Ukraine happens, Impeachment happens, Coronavirus happens and the 2020 election happens.
This is why he allowed them to get away with the 2018 Midterms and take the House. Hammer and Scorecard were used again. He knew they'd go after him. "I gladly take these slings and arrows for you."
So come to the 2020 Election he allowed them to take it this time. In order to prove all of this, he had to lose.
In order for Trump to win, he must first lose. Dark to Light. Sun Tzu: Appear weak when you are strong. You must lose small battles in order to win the war.
The Democrats projecting their crimes on to Trump knowing he wasn't guilty of them was to convince the American public and the world to look in the wrong direction.
This is why Q say Future Proves Past. Think Mirror. Everything said 3 years ago beginning 27/28 Oct 2017 applies to now.
There has never been a time were President Trump has never not been in control of this plan. Sit back, grab the popcorn and enjoy the show. It's going to be BIBLICAL.
