Puerto Ricans in Chicago are paying close attention to today’s Democratic primary on their ancestral island, but with some misgivings. We report from our West Side bureau.

Chicago has more Puerto Ricans than any other U.S. city except New York. Anchored in the Humboldt Park neighborhood, the community stands out for supporting underdog causes like legalization of undocumented Mexicans and political rights in Puerto Rico.

Residents of that Caribbean archipelago are U.S. citizens but have no seats in Congress. And they can’t vote in November’s presidential election. But they do have a voice in who gets nominated.

MALDONADO: This is the first time that some attention has been given to the primary election in Puerto Rico by the national media.

MORALES: At least Puerto Rico is being talked about.

Marisol Morales helps run a service-learning program at DePaul University. She’s hosting a house party this afternoon to watch the returns.
