I understand what sweep up means... I was saying that's not what I'd want to be doing and it isn't what I was attempting to do.

As for useful idiot, you're literally assuming you know what you claim to be true... Just like you said, what you think or what I think doesn't matter. I'm not "helping" them by my comment suggesting that we might end up embarrassed if they do end up having actual proof he's a "left winger." I'm of the mind that this is unfortunately more likely than not to be the case.
