Not sure why this applies to Trump any more than it would Feinstien or Reed on this topic...
Really?
How about because Trump has had multiple bankruptcies of casinos specifically, after personally profiting handsomely by paying himself off, literally, even while being caught taking illegal loans to cover debt payments when cash flow was inadequate. He personally bragged about the many, many millions of dollars he "pulled out of Atlantic City," even as his remaining ownership rights were lost in bankruptcy.
How about because Trump has been involved with 4000 lawsuits, with about 75 of them expected to be still active when he becomes president, even after the recent settlement of the fraud lawsuit for Trump "University," where he had to pay back $25 million to refund all the "tuition" taken from students?
How about because Trump is the first person heading into a presidency who is refusing to take any meaningful steps to reduce conflicts of interest?
He has the strongest and best-documented history of self-dealing and self-interest of any person heading into politics in a major person in my memory.
Plenty of politicians have made some money after gaining power and knowledge and contacts in office... some legitimate, plenty not... but Trump's track record is one of playing people, playing the system and - let's be honest, since he bragged about it, buying politicians.
He has already been admitting publicly that he played the voters, after all! People counted on him to "lock her up..." he claimed he would, during the national debate. After becoming president-elect, what did he say? "No, no. That played well before the election. Now? We don't care."
Quite plainly, conservatives have been played by the man who spent a lifetime playing people.
