Silly remark, even if you have, say, fifteen parties (like in France), you will still have only two parties able to win the elections. So it leads to nothing different, except potential surprises in the first round of the polls. (Like Last year, when the extreme right-wing made it to the second round)

Usually, you have the leader of the left-wing parties against the leader of the right-wing parties, the smaller parties following one of the two sides. It doesn't change much, does it? And when you have 16 candidates for Presidency, representing 15 parties, what is the point? Only two of them stand a chance of winning, and many voters choose their candidate not because they believe he would make a good president, but for other reasons and almost randomly.
