I'm tired of this and I doubt this guy or anyone with an ounce of sense believes this. His head is not in the right place. Obama is a radical and what he is doing is intentional. Time for these people to start telling it like it is.
A common rhetorical practice is to grant a premise that you don't necessarily agree with if it doesn't harm your argument. Especially if it helps bolster your argument.
In this particular case, it comes out as "I'm not attacking his motives -- in fact, even if we concede his motives are pure, he's a failure due to incompetence."
