There's no one in my quadrant available for me to vote for at a general election (greens don't run here, and I'd be loathe to vote for them anyway, due to the environmental stuff). So I previously voted Liberal but I think it'll have to be Labour in future.
But yeah, the fact that the majority of people who take this test end up in the bottom left quadrant and all the mainstream parties are in the opposite quadrant suggests there's a problem somewhere. Or people just really do vote for lower taxes and nothing else.
