Here are some of the differences:
* Puerto Ricans cannot vote in presidential elections. They can only vote in the primaries for the presidential candidates of the two major parties, but they cannot vote in the general election.
* Puerto Ricans do not have full representation in Congress. They have one non-voting representative in the House of Representatives, but they do not have any senators.
* Puerto Ricans cannot elect their own governor. The governor of Puerto Rico is appointed by the President of the United States.
These differences in political rights are due to the fact that Puerto Rico is not a state. It is a commonwealth, which means that it has a special relationship with the United States. Puerto Ricans are US citizens, but they do not have all of the same rights as those citizens who live in the 50 states.
There have been several referendums on whether or not Puerto Rico should become a state. However, none of these referendums have been successful. The main reason for this is that there is a lot of opposition to statehood from both Puerto Ricans and those in the United States who do not want to see Puerto Rico become a state.
The issue of Puerto Rican political rights is a complex one. There are many factors to consider, such as the history of Puerto Rico, the relationship between Puerto Rico and the United States, and the views of Puerto Ricans themselves. There is no easy solution to this issue, and it is likely that it will continue to be debated for many years to come.
