“Did Cheney really have to give Barry credit?”
Yes, Cheney had to give credit to Barry because that’s what a public servant should do. OTOH, you could add up the gravitas of Barry + Joe Bite-me + Jimmah Cahtah and it would not fill a thimble; those three are just miniscule little rabbit turds, a small rabbit. They will never credit a successor because they are all three shriveled little weasels inside.
Cheney didn’t send any biggies Barry’s way, only said he did the right thing when the option came up. This President’s numbers were as low as they have been at that time, so it seems he pushed to have the event happen. Obama has had the information on OBL since last fall..and that has been in the news also.
