McCain finally calls Obama a liar

It’s about time.  I wonder if this conventional wisdom that going negative is bad is all that conventional or wise?

The GOP presidential candidate told a campaign rally: “Sen. Obama has accused me of opposing regulation to avert this crisis. I guess he believes if a lie is big enough and repeated often enough it will be believed.”

In some of the harshest language yet, McCain said the campaign comes down to a simple question: Who is the real Barack Obama?

McCain drew the loudest cheers when he said the Democrat has written two memoirs but “he’s not exactly an open book.”

Obama is right - a lie will be believed if it is repeated enough. Obama is no fool. He’s observed how things work and his handlers have probably wrongly assured him he can get away with lies. That is about to change I hope.
