That's not much of a democracy.
well, you are free to vote for whoever you want
but we have a lot of parties and because a lot of people dislike politicians, they vote for someone who will never be ellected
for instance we have a rascist party who are blocked by all the others so they will never be in the government
a lot of people vote for them, not because they are racist but because they want to send a signal to all the others
voting should be a right not an obligation
