I've just used their tool to look through who I should vote for. It actually came out as I was expecting - lib dem with a leaning towards labour, which is about right as I generally describe myself as left of centre.
What I thought was interesting was their results at the end. It shows your own own results, but also gives a table based on your constituency.
Currently, my tory MP has a 66% majority - but based on 10 people (don't start, I know) - it actually says that based on what people would choose as their preferred policies, the green party would be the preferred option. This makes sense because our local elections saw the greens/lib dems join a coalition.
But what I thought was really interesting is the vote for policies tool then gives an insight into policy preferences for England and then nationally.
Based on almost 23k survey responses, it actually shows a majority for Lib Dem, not Labour - I thought this was hugely interesting, and I have no idea how this compares to the accuracies of the polls, nor how accurate this website is.
But it does suggest that no one should take anything for granted!
