Context: You know, the Donald is not really a plans guy. He’s not really a facts guy, either. He calls himself a business guy, which is true, but I have to say, I know plenty of businessmen and women who’ve achieved remarkable success without leaving a trail of lawsuits, and unpaid workers, and people feeling like they got cheated.
Does anyone really believe that a guy who’s spent his 70 years on this Earth showing no regard for working people is suddenly going to be your champion? Your voice?

If you want someone with a lifelong track record of fighting for higher wages, and better benefits, and a fairer tax code, and a bigger voice for workers, and stronger regulations on Wall Street, then you should vote for Hillary Clinton.
