Syriza as Greece's number one party in the city of Chalkida and the surrounding regions - something that was unthinkable until the May 6 election.
An estimated 6,000 jobs have been lost in the region - once a centre of industry - over the last nine months. And many voters now feel Syriza is the natural choice.
On Sunday the far-left party is hoping to deliver a final knock out blow to mainstream politicians by winning the general election.
Al Jazeera's Andrew Simmons reports from the city of Chalkida.
