We do all the time.. Our Prime Minister comes from and leads the party that wins the election, and with proportional representation, it is quite common for a government to win office with less than 45% of the popular vote.
KF is 100% correct, if you have simply "one person one vote" and not a system like your Electoral College, then the cities will determine government every time.
