Look at his name. Guess what his base is composed of...
Look at his district, FL-28. It's everything south and west of Miami, including the Keys.
FL-28 is 73% Hispanic, 15% White and 9% Black.
Despite FL-28 being only +2% GOP in registrations, Carlos won 65-34 against each of the last 3 Dem opponents (including the incumbent)... and the 2020 opponent was also Hispanic.
FL-28 was mostly Blue from 2012-2018, but not by huge margins. Hillary 2016 was the biggest winner, at 56-40. In 2020, it went from Trump by +6 (53-47)... in 2022 and 2024, it was overwhelmingly Red (65-35-ish).
It seems to me that he has helped bring the entire District pretty strongly to the Right (as the rest of the nation has been slowly trending).
