why not test them? Those that pass get a vote.

I don't think you meant the electorate but maybe that would be a good idea.

After all one must pass a test before driving a car, and who we vote for is more important than driving.

I think I am petty safe in saying, although I will get shot for saying it, a large percentage of the electorate probably don't understand the reasons why they might choose one candidate rather than another.

Many vote labour because its the working mans party or conservative because it not the work mans party, or Social Democratic because they should be given a chance.'

And, its probably those who don't understand why they should vote for one party or another, who's vote decides who get elected.
