Fine, let them think that. It's missing the point.
To win, Youngkin needed Biden voters to vote for him. Those are not the voters getting sucked in by CRT. That is the meat he tossed to the base who was voting for him anyway. But it suckered McAuliffe into speaking out against parental involvement in their kids education. Frankly, it was a mistake made by a lackadaisical campaign, from the error to the cleanup. And it might cost him the election. Just that one thing, end of story.
It could have been extremely effective to call out CRT as a non-issue, agree that it shouldn't be taught to young kids and support parents and their right to impact educational choices. But instead McAuliffe fell into that trap of over-catering to the far left perhaps, or maybe just not taking Youngkin seriously, I don't know. But if he loses it's because he tried to just sidestep the many educational issues that were absolutely real, and just yell Trump Trump Trump for the past 2 weeks.
Newsflash - a few months ago like half the country voted for Trump. He's not the magic poison the left thinks he is. That's the reality.
