It seems to me that according to Jewish Law, one should vote Porush. The Rambam states in the Laws of Kings and Wars (1:9) that:
וכל מי שאין בו יראת שמיים, אף על פי שחכמתו מרובה, אין ממנין אותו למינוי מן המינויין שבישראל
And anyone who is not God fearing, even though his wisdom is great, is not to be appointed to any position among the positions of (the people of) Israel.
Disclaimer: I am far from a Torah scholar and I haven't asked one if this law applies to the municipal election. Food for thought, and a question for your local Orthodox rabbi.
