Another lame-o inside joke?
Do I have to explain it to the ruhtards? Ok, fine.
See, the business owner is boarding up his shop because the animal democrats like to throw tantrums and destroy more successful people’s livelihoods. And because Trump will win, we’re all expecting the animals to show their asses on Tuesday night. So the business owner, who most likely voted for Trump, is painting “Harris/Walz” on the plywood in hopes it fools the degenerates into thinking they voted for the candidate the looters and vandals support.
Hope this helps. I could dumb it down even more for you if you’re still struggling.
