The difference in margin betweeen Ricardo Rosselló and Jenniffer Gonzales here is best explained by Candidate quality, with Ricky (less conservative than Jenniffer) outperforming her in the State's urban areas, especially Trujillo Alto and Hormigueros.
By contrast, Jenniffer did best compared to Richy in the conservative area around Fajardo and Patillas, the latter home to PPD Gubernatorial candidate David Bernier.
