Two party systems work better in that a majority of the voters are behind one party or the other. There have been a few instances when a third party candidate caused a candidate to be below 50 % (Clinton). Many states require run offs in elections where a candidate did not get 50 % of the vote. Multiple party systems allow governments to be formed which do not represent the people. In recent history, this has benefitted leftists far more than conservatives (think Canada). I believe in the two party system and would not wish to have a multiple party system.

And you think the present government DOES?
