Hi Lila good to talk to you again...
IMO, even if Republican John McCain is lying through his teeth, the repubs will believe every word that falls from his thin lips. Obama cannot correct these lies, Obama cannot call out Republican McCain on the Lies, and Obama cannot keep saying, "John is Right." WHEN Republican John McCain tells a truth. That is like correcting a child while trying to maintain his self-esteem. This is not a good political tactic.
Obama needs to forget about trying to argue with a liar, and stick to speaking from the heart. That is what he does best, and it is most natural for him to simply Tell the Truth.
Obama, in your next debate, when Republican McCain says uses democratic talking points... do not credit him. Just take it and run with it! In other words if Republican McCain mimics what you are saying just say "...and to elaborate on that point..." Tell the Truth Obama, and (as one of the guys at work said) "The momentum of it will push you through"
My friend Doc relays this advice... "Do what you do, and those who like what you do will be there for you."
