re: He has an opportunity to stop this kind of hate because he is a man of great influence. Lets see if he uses this opportunity to do that.
That's not his job.
His job is to get elected President. If making a statement like that would help get him elected he should do it. If it would hurt his chances of getting elected then he should not.
Once he is elected he can use the office and his art of personal persuasion for battling hatred.
but I got news for you...There's always going to be hatred out there somewhere.
