Please don't take this as support for Ted Nutsack, but:

The specific line about "cutting off heads" was about "cutting off heads" in November , which makes it a fairly plain, if miserably phrased, reference to voting against somebody.
The rest of the speech was so indefensible that it may not be worth making that distinction, but I guess I can detest the guy enough for what he really said without pushing things further.
