It would not matter to an Obama supporter.You can tell them he lies, show them where he lied. Show them the lie he told. They still won’t believe he lies. They will tell you right quick that if the Republicans would leave him alone, he would straighten up what is wrong with the Country right now. You are just wasting your time pointing out the truth about Obama to an Obama worshiper. But it is your time
They still won't believe it, but knowing that everyone else on your mailing list is seeing it, and that they aren't all obots will bother them to no end.
