It advocates a mixed economy and encourages property owning. The Labour Party is the major leftwing party and is also one of the two governing parties and it has been in power for three terms. It is mainly supported by people from the workers and middle class. It advocates workers’ interests, democratic socialism and social equality. The Liberal Democrat Party is the leftwing party. In the past, it is one of the two main parties, but now it has been declined. The twoparty system is the developmental product of the British parliamentary system. In this system, many things can realize equal. There are two main political parties in America: Democratic Party and Republican Party. “It suggested that there will always be twoparty system in the United States simply because it works well to get two names on the ballot for every office.” [3] If politics is about winning and losing, then it is obvious that who wins and who loses. In the past, the Democrats advocated policies of benefiting famers and encouraging education. However, the Republicans have paid more attention to business.

In American election, there is a system called “winnertakeall” which means the candidates who get the most votes will get all the votes and win.
