Wait a minute, I thought you said Obama should have credited Bush. Which is it, share credit it with his predecessor or don't mention any credit for any executive decisions?
Or is it maybe that there was absolutely nothing that Obama could have said that would make you happy because you wish it weren't Obama who oversaw the taking of OBL?
False dichotomy. It is entirely possible to give credit to others and not mention your own role. Good leaders do it all the time. If you think I care one iota about who was in the White House when our military succeeded in killing Bin Laden, you are projecting your own mindless partisanship onto me, that's all.
