You could be right, I never checked into where the slogan began. I'll disagree on the cost, the numbers, the political pundits, even democratic strategist and after action folks clearly show and admit the slogan cost the Democrats 13 house seats. Now the cost of losing 13 house seats may be well worth it with the reforms implemented. I suppose that is in the eyes of the beholder. But election result wise, I'd have to say no. Reform wise, perhaps it was.
The slogan probably cost Biden some votes. What it showed was the GOP was able to tag the Democrats with that slogan and convince a certain amount of voters that was exactly what the Democrats wanted to do, to do away with the police. The polls show this clearly.
Now losing 13 house seats is something the Democrats could afford. Not something they wanted since every poll was showing the Democrats would gain seats, some estimating their gain at 20 plus. Big difference from a 20 plus gain and a 13 seat loss.
What changed, congressional elections are more local, folks like their local police and don't want to see them done away with. Nationally, the exit polls show that defund the police added 3 points to Trump's popular vote total. Again something the Democrats and Biden could afford.
What I never understood, still don't is why the Democrats let the Republicans tag them and convince folks that doing away with the police is what the democrats want. The only thing I can come up with, nothing to back it up, just a shot in the dark, is Biden and the democrats didn't want to do anything to make their most loyal voting block, blacks mad at them. Especially since it was them who lead the charge with Defund the police.
I may be completely all wet there. But trying to come up with reasons is something I do. As it was, 12% of blacks voted for Trump, the most any Republican candidate since Ford back in 1976 received. Ford received 15% of the black vote. So perhaps, some blacks didn't want the police defunded and done away with. History is interesting in this and the after effects. But I won't get into that. This is getting much longer than I intended.
