The far-right Swiss People's Party put up shocking anti-immigration posters four years ago and took the largest share of the vote in the country's modern history. So they're doing it again this time around.
A poster in the German-speaking part of the country shows black boots marching over the Swiss flag.
One in French-speaking areas shows a condom plastered over the European Union's banner, proclaiming "Swiss protection against the European virus."
And the scare tactics seem to be working.
The anti-immigrant party looks set to repeat its 2007 election victory on Sunday, with opinion polls putting it in first place as voters cast ballots for the federal parliament.
A Eurobarometer survey this month put the party, known as the SVP, far ahead of its main rivals, with just under a third of people saying they would back it.
The Social Democrats (SP) are in second place, with about 20% support, followed by the FDP Liberals, the Christian Democrats and the Greens.
The People's Party won the biggest election victory in Swiss history in 2007, after a controversial campaign that blamed foreigners for much of the country's crime.
The nationalist party rode a wave of anti-immigration sentiment to gain 29% of the vote - about the same that it is getting in opinion polls this month.
Switzerland's political system requires consensus, making radical government policies unlikely, regardless of the election results.
But anti-immigrant sentiment helped fuel a 2009 ban on the construction of minarets, the towers usually built next to mosques for the traditional call to prayer.FULL STORY
