John McCain, Hillary Clinton, and Barak Obama were walking down a Washington DC street when they came upon a homeless man.
John McCain, gave the man his business card and told him to come to his office for a job. He then took $20 out of his pocket and gave it to the man.
Hillary was very impressed, so when they came upon another homeless person, she decided to help. She walked over to him and gave him directions to the welfare office. She then reached into John McCain's pocket and got out $20. She kept $15 for her administrative fees and gave the homeless man $5.
When they came upon yet another homeless person, Barak told him to "have hope...change is coming..." and gave him nothing.
Now do you understand the difference?
