A nasty campaign for the White House is almost over

The last few days may seem like forever, with candidates, surrogates and new TV and Internet commercials almost impossible to avoid. Donald Trump is telling himself to "stay on point," which means claiming, untruthfully, that Hillary Clinton is under a "criminal investigation." He’s trying to lower the turnout in urban centers, while Clinton is trying to increase it -- claiming that Trump is biased against blacks and Latinos. Do early voting and last minute polls mean the dynamic is really changing with so little time left to go?
