Very difficult problems, but in my judgement, all solvable if we generate the country in the kind of bipartizan political cooperation and political courage that will be necessary to fix them.

One factor contributing to the two-party system in the United States is the single-member district system of electing Representatives.

Elaborating, Armstrong said a bid in America's two-party system could alienate some of his fundraising partners.

Saying we should keep the two-party system simply because it is working is like saying the Titanic voyage was a success because a few people survived on life rafts.

When we say that we have a two-party system in the United States we do not mean that we have only two parties.
