Race and prejudice in politics

I don't understand how someone could NOT vote for someone because of their skin color. I am listening to the news and reading articles of people who say they won't vote for someone who is black. These people who say they are good people, Christian people, and yet they have hate in their heart and have the cancer of prejudice in their heart. No one can say they follow Jesus, love the message of Christianity, and hate someone because of their skin color. God made everyone of every color and race. We are supposed to get along and be kind to each other. We are supposed to support one another and be happy for someone who is doing well.
