Swiss Buttocks v. Muslim Headscarfed Hags

Swiss "anti-immigration" ad: What We Have-What We'll Get   Euro Heads Explode

What? Clog Swiss beaches with this? In advance of a coming referendum, the antis came up with this campaign ad which offers (rollover) a choice of sweet Swiss buttocks on Lake Zürich beaches, or  headscarf-wearing Muslim women bathing in filthy water.  A bit over the top, but I'm laughing (actual nose bubbles)  at the whole idea; if you're not - I guess our first date would be a bust. Anyway, the referendum is not anti-immigration, as I first imagined; it's to decide whether foreigners who have been found guilty of murder, rape, drugs trafficking and other serious offenses should be deported.  I wonder if the Swiss system allows for an Eric Holder and activist judges to "moot the vote" should this common sense proposition pass?
