"2010 is not just a choice between Republicans and Democrats. 2010 is not just a choice between liberals and conservatives. 2010 is a referendum on the very identity of our nation"

This quote by Marco Rubio suggests that the 2010 election is not practically choosing between political parties or ideologies, but rather a referendum on the identity of the nation. He suggests that the election will have a major effect on the future of the nation and the instructions it will take. He is recommending that the election is a possibility for the people to decide what sort of nation they wish to be and what sort of values they want to support. He is highlighting the value of the election and the power of individuals to form the future of the nation. He is motivating people to take the election seriously and to make their voices heard.
