I only translated the first one, and he is quite typical of persons born in Portugal. They are overwhelmingly concentrated in New Bedford and Fall River. It is a quite atypical pattern compared to other countries, particularly European, which almost invariably have a primary concentration in New York City.
Also about half of those who report they were born in Portugal reported that they were born in the Azores. In the US Census, place of birth is a write-in, and there are codes for many internal areas, which the Census Bureau can tabulate various ways. So it is likely that the person responded "Azores" rather than "Portugal - Azores" or was prompted by a census taker, who followed up with a question of 'Would that be from the Azores, or on the mainland?'
There is a strong difference between New Bedford and Fall River in this regard, with New Bedford respondents to be more likely to report Azores, though the two cities have about the same number of Portuguese and the same total population.
My understanding is that a great number of Azoreans come to the US via the mainland. Perhaps they migrate to Lisbon, and don't feel at home, and so emigrate.
So maybe the questions should actually be: "How do Azoreans in southeastern Massachusetts vote?"
There is a much smaller concentration of Portuguese Americans in the Central Valley of California. They might be more Republican because of their political success.
