In every State that doesn't have same day registration, any and every voter on the roles can and is supposed to be challenged before the election if either party thinks they are voting illegally. That is the rule in everyone of those swing states. Every voter could have been challenged for months. If this thing with Crowder was remotely true, the GOP could have gotten them struck from the day after they registered (when they show up on the voter registration).
Anyone can get voter rolls, the fee is small and investigation is clearly not hard if Crowder did it. Pulitzer he isn't.
Trump isn't a problem because he isn't popular or good at deflecting, and beating up on the Media. His problem is that he has no follow through, and never makes sure the actual work is done. He hires and values based on loyalty and usefulness, but not on the sort of nuts and bolts competence that could have caught this sort of thing. So rather than giving his local faithful the resources to take care of this or spinning of a PAC to do the same for each state, he does more bloody add buys and uses half the stop the steal money to pay down campaign debt.
I hate the man for personal reasons (Wrong me, and I shall forgive, Wrong my family and you are dead to me until you at last apologies to them in person.) But I cannot help but recognize his strengths.
He's an improve guy. It makes actually fighting him like punching smoke, but it means anything that takes a plan has to have someone else to catch it or it will fall on the ground. And this was a known thing and wouldn't have been hard. But no, lets blow more money on useless TV ad buys.
