Fish in a barrel pt 2

The torture ban passed 90-9, and the Bush administration has been threatening to veto. 90 votes isn't even close to the cutoff for overruling a veto, so the administration has to have known for a long time that they didn't stand a chance. So why did they veto it? "We'd just like to make a symbolic gesture that we approve of torture, and also exacerbate divisions within our own party by forcing Republicans to help overrule the President." This could not make less sense.
