First of all, WD, and I say this with love, using ibb is a crime in and of itself when there are other image hosting sites that don't butcher the pictures beyond all recognition.
Apart from Spark’s behavior towards women, he is, simply put, a criminal. He committed voter fraud and was convicted of such in a court of law. A convicted felon should not serve in the Senate. As Senators, we should hold ourselves to the highest standard of behavior. Spark has not met that standard, and for that he must be expelled.
Lovely sentiments about the criminality of Spark's past, but since they amount to exactly zero words of the resolution I'm inclined to think those are not germane to the issue at hand.
