I would be real careful when challenging Trump, especially his Tax Returns. Chances are extremely HIGH you will lose and be forced to Admit you are a fool. Trump is a smart cookie, underestimate NOTHING, Take NOTHING for granted.
I’m sure his taxes are legal. I’m more concerned about his electability if it becomes known that Casino’s are NOT the dirtiest business with which he’s involved.
Dem’s and MSM have largely laid off Donald, keeping their real powder dry until the general. If you think they made mincemeat out of Too-Many-Houses-To-Remember-McCain, or Cold-hearted-Vampire-Captialist-Mitt, they’ll pummel Trump mercilessly and no-one will take a second look at Hillary.
