No Wikipedia explicitly states that people from Spain are not included;

"The term commonly applies to Spaniards and Spanish-speaking populations and countries in Hispanic America and Hispanic Africa" I.e. not mainland Spain.

“The term commonly applies to Spaniards AND…”

This is not a complex sentence.

A friend in college from Spain had way too much fun pretending to be stereotypically hispanic and would insist that he had more a claim to it, being from Hispaniola, after all.

To be pedantic, if he was from Spain, he would be from Hispania[1] not Hispaniola[2].
