Eric "I vote Labour because my family always has" this happens with other parties but seems to float Labour the most. It's an absolutely ridiculous and irresponsible way to vote. I wonder whether similar happens elsewhere in the world and with which parties.

Martijn I wouldn't be surprised if this applies all around the world. Research has shown that your first vote is very important, if you vote the first year you are allowed to you are more likely to keep on voting in future elections. So if your parents take you to your first vote and influence what you vote, maybe you are more likely to keep voting that same party?
