You are exactly right.
I believe the purpose of the polls showing Hillary with a big lead is to be cover for the massive election fraud we will experience.
To be honest, I do not believe there is any way to fight it. Even if Trump gets 80% of the actual vote, the Dems just have to rig voting in a few battleground states to show a narrow win. This will give them the electoral votes needed to win the race. The fake polls provide cover.
Well, we still have a Bill of Rights.
