Howard's interest rate gaffe? Did any Australians see this?

This makes me really angry, who cares if John Howard got it wrong, he is so busy running our country he doesnt need to know the exact interest rate. Kevin Rudd got it right, but he also proved that he had seen John Howard's interview before his own was conducted, talking about the so called debate 'worm' which John Howard mentioned in his. Tracy Grimshaw told John Howard the correct interest rate and Kevin Rudd would have seen that too. The whole interview was biased to portray John Howard in the negative and Kevin Rudd wasn't given any grief. It really annoyed me.
