Social Democrats have held a steady lead as Sweden’s largest party in the run-up to the September 13 parliamentary election, with polling averages placing their support near 28-30 percent against roughly 18-19 percent for the Sweden Democrats in second place. This positioning has produced a consistent 9-10 point margin that aligns with trader consensus for a 7-10 percent victory margin. The bloc contest between the centre-left opposition and the right-wing Tidö parties tightened in the final weeks, yet the gap between the top two individual parties remained largely stable amid campaign focus on the economy, crime, and immigration. Late swings in turnout or unexpected strength from smaller parties could narrow the margin, though current evidence from exit polls and preliminary counts points to limited movement from the established range.
