That is correct. People will look at the returns for him and his businesses and stick to their sides talking points.
I think once the returns are released you will see some tax planning that is aggressive, legal, and optically a challenge for the POTUS. I think you will see individual and business returns that consistently show little tax profits. This will be an optics challenge for the POTUS and probably an ego blow for him since most people cant or wont understand his tax posture vs his claims.
