Party leader satisfaction ratings and election outcomes

In this post, Ruth Dixon argues that, in future elections, measures of party leader satisfaction are worth looking at in more detail, as standard voting intention polls led many forecasters astray in 2015.

As the plot below makes clear, satisfaction with party leaders of the two main parties would have predicted the outcome of the last nine UK general elections, […]

If not polls, then betting markets?

In this post, Chris Hanretty, Ben Lauderdale and Nick Vivyan investigate the predictive performance of the betting markets relative to their forecasting model. 

The failure of the opinion polls to accurately estimate national vote share has led some to suggest (here, here) that we should instead look to betting markets as a way of eliciting information about election outcomes.

The new “skew” of the electoral system in 2015

Historically, the electoral system has tended to help Labour in the way it translates votes into seats. In 2015, the skew changed, giving a significant advantage to the Conservatives, argues Tom Lubbock.

Tactical voting and the alternative vote in 2015

The growth in minor party support in the 2015 general election looks set to create very difficult tactical voting dilemmas in some constituencies. Meg Russell reflects on how a move to the Alternative Vote (AV), which was rejected in a referendum in 2011, might have eased such dilemmas – suggesting that a messy election result could unexpectedly put AV […]

Would the Conservatives have been better off under AV?

The 2011 Alternative Vote (AV) referendum was rejected by a substantial majority of the British public, and was opposed by the Conservative party. In this post, Chris Hanretty, one of the team at, investigates whether the Conservatives would have benefitted in the 2015 election from an AV electoral system. He finds that it is likely that the AV […]

Focus on… the Midlands
