Anyone who still supports George Bush would still let Michael Jackson babysit their kids.

Meaning of the quote

This quote is saying that if someone still thinks President George Bush was a good leader, then they probably wouldn't have any problem with letting the famous singer Michael Jackson take care of their children. The idea is that someone who still supports a controversial leader like Bush would also be willing to trust someone like Michael Jackson, who was accused of inappropriate behavior with children, to be around their own kids. It's a way of suggesting that the person's judgment is not very good.
