The President is a liar. The Democrats did not have the same intelligence as the White House did.
And that's all any Democrat has to say. Don't try to explain it. Don't let the Republicans misdirect you into the details or distract you in any way. Just keep hammering the same line over and over and over because the public already knows it's true: The President is misleading the American people. The Democrats did not have the same intelligence as the White House did.
Rinse and repeat all the way to 2006.
Again, establishing a fact is not the same as persuading others to accept that fact. The fact - the president is a liar - has long been established. Now, how do you get others to accept it? Say it: The president is a liar. Say it again: The president is a liar. And when someone demands proof, you repeat: The president is a liar.
