That 500 dollars came in long ago, before Paul even knew who that person was. The money has already been spent. If he were to give that racist guy money now, it would like giving money to go towards what Don Black supports, instead of going towards something GOOD. And it also would be like saying people who give to his campaign have control over him. That may be the case for people like Hillary, but not for Paul.
This story is old news. The only reason this is being rehashed is because Paul is doing well - he just had a 6 million dollar fund-raising day, he has been doing lots of interviews and gaining more support. So the haters and others are nervous, and the attacks are coming in...In fact, today (as is evident on this site) his haters are in full attack mode. Unfortunately for them, they have nothing on Paul personally, because he is a good man, so this is what they're throwing on the wall, to see if it will stick.
Nothing is going to be good enough for some people. Personally, I like that he hasn't been kowtowing to his detractors who are pressuring him to do what they want. They will never be satisfied, because some people (like some on this site) hate him with a passion, and they're just trying to find anything to bring him down, because he has growing support.
Oh please.
