Say you’re well behind in the polls. But you have an ace in the hole, that being the intelligence service of a foreign power. What do you do?
1) Claim the election is going to be rigged ahead of time
2) This gets nearly everyone, especially Democrats and anti-Trump Republicans, to go on record as saying that is terrible, that of course the election isn’t rigged and we should accept the results.
3) Rig the election, with the help of the aforementioned foreign power.
No one can dare claim the election is rigged, at least from the non-Trump side.
Game, set, match.
