Political scientist Sofie Blombäck on environmentalists splitting their votes: "Strategically"

In this year's election, 34 percent of Swedish voters split their votes, according to SVT's polling station survey, Valu.

This can be compared to 2006, when 27 percent voted for a different party in the municipal election than the party they voted for in the parliamentary election.

At the same time, there are large differences in the electorate.

According to political scientist Sofie Blombäck at Mittuniversitetet in Sundsvall, it is usually the most politically interested and informed who split their votes.

Not so deeply convinced

The majority of vote-splitters are among the Green Party's voters, where 57 percent voted differently.   

- The Green Party is often one party among several that their voters think about and then they might choose to split their vote.

But it is also about the voters' ideological convictions.

- The Green Party does not have very many deeply convinced supporters who would never imagine voting for any other party, says Sofie Blombäck.

The most loyal voters are with the Left Party and the Social Democrats, where 24 and 25 percent respectively choose a different party in the municipal election than in the parliamentary election.
