Trump is smart to make this an issue now. It helps him build awareness of the corruption in Ohio politics, so when he publicly challenges voter fraud or attempted voter fraud in Nov. he will be able to make a stronger case.
No. It gets him off message whining about fire marshalls. The people don't care about this. They are electing a President. He should stay focused and disciplined and either let surrogates deal with it or take care of it privately. Trump is a pro at taking care of stuff like this.
Actually, I think Trump should embrace it. He should proclaim that hundreds/thousands were turned away from his event at X venue.
