Sneaky Chris Stirewalt on Fox Hedges His Bet Fearing Red Wave by Saying Polling Will Be Off 4% Either Way

Translate:

For the first time this election season, Chris Stirewalt of Fox News said the polls are likely to be off by 4% either way (according to previous election polling he says), so why is Chris only now saying this, could it be that the red wave is becoming obvious and it’s his way to get-out-of-the-way, to be able to say that he predicted something without saying he was expecting the red wave?
