I have no problem agreeing with you on this (as I do about 99.9% of the time), but it appears he's trying to sabotage the 1/5/21 runoff election to help the Democrat candidates. I'm sure he meant it in the way you see it, but that's not how the leftists will play it.
The leftists have already played it by falsely saying that Wood is calling for a boycott. He is not. His exact words were:
Threaten to withhold your votes & money.
The threat of losing a constituent's vote should always hang over the head of any politician. It's called 'accountability'. But threatening to do something is one thing. Following through with that threat is something else. Wood is prompting for their support. He hasn't yet turned his back on them.
But I cannot emphasize this enough: If the system isn't corrected, then it won't matter whether anyone votes for Perdue and Loeffler or not. The Democrats are harvesting fake ballots, and they know how to put malware on select voting machines and tabulators. And they already know how many votes they will need to win.
