We cannot and will not realize our full potential as a nation unless we have both parties working to forge a new sense of shared association that can enable a much more diverse America to journey together into the 21st century. Today, sadly, only one party is in that business.
Friedman ties in his purpose once again at the end. He accentuates that the nation as a whole cannot develop or reach its full potential until the two political parties work together; until they both place importance to the diversity of the nation. This allows him to demonstrate that without change occurring in the Republican party, change cannot occur in the nation. He shows that the Republicans need to change and the parties need to work together to make nation better. He places emphasis to show that we are well into the 21st century and yet we are still not treating everyone equally, showing the importance of what his point of view is. Then he ends with a sentence that is almost demoralizing to emphasize that we cannot become diverse until the Republican party changes.
