Obama is lying:

Or is it McCain who is lying:

Or could it really be much simpler than that.  Perhaps they're both lying... they are politicians aren't they?  That's the one thing politicians are guaranteed to do.  Frankly, this is staring to feel more and more like a playground fight between two immature kids.

Stop calling me names!  I am not a liar!  Stupid head!

I can't wait until one of them gets into office and bites the President of Russia on the wrist and then kicks him in the shin for giving him a mean look.
