Many scholars of politics have proven that two party systems are the best, but in my opinion I don’t think it is the best because it doesn’t really give room for proper democracy because it’s just two persons that stands the chance of contesting for elective offices, the aspirants just come from two parties only and it makes democracy unbalanced in the society.
In a democratic state I think it’s perfect for multi party systems to take effect and come to stay because looking at the society generally you will see so many are interested and loved by their people but they ain’t given a voice simply because they’re not well connected. Multi party systems allow the grassroots movement have a strong voice and high level profile.
The two party system has a lot of advantages but I believe that it is not the optimal system. Having a two party system feels a bit like looking at everything in black and white, you are either for something or against it. But the world is not black and white, there are plenty of grey areas. Having more than 2 parties, like maybe 4 or 5 would make if easier for the voter to fully identify with one party.
