He didn't admit anything. He and all the rest of them are still lying. They didn't "get it wrong". That implies an honest attempt to get it right. Instead, they intentionally lied to us in an attempt to manipulate the vote. They lied then and they lie now! They're worse than worthless!
And they’re trying to prepare the ground to do the exact same thing the next election. All they want to “learn from this” is how to get better-more undetectable-at it.
You said it better than I could, great post.
