such a failed 'business' man that he bankrupted many casinos with ties to Russia
People misunderstand what this was really about, and why he kept doing it. Those casinos allowed him to launder billions of dollars of Russian Mob money, and exploit the casinos into insolvency, and then just walk away, and stick everyone else with the bills.
It's not so much that he's a bad businessman (although he is), he's a CRIMINAL businessman, otherwise known as a Mobster.
I hear Trump didn't like it when Putin tried to date-rape him. Not that it offended him all that much, but Trump was quoted as saying "I do all the raping around here."
