Maybe it was the compliments they'd just given each other. Hillary Clinton and Donald Trump shook hands after the debate ended, something they refused to do 90 minutes earlier. The debate was especially icy at the outset, replete with talk of sexual impropriety and Trump threatening to jail Clinton over her erased emails. But the St. Louis rumble concluded with a voter asking them to say something nice about each other. Clinton's and Trump's families quickly joined them on stage as the debate wrapped up. The candidates greeted their relatives and then circulated the room, which is filled with undecided Missouri voters as well as supporters of the two campaigns.
