Hernandez is one of three Co-Chairs of the Virginia Latino Caucus, helping lead the growing bloc of Latino legislators in the General Assembly. He won re-election in 2025 with 61.3% of the vote (up from 55.7% in 2023), signaling a strengthening Democratic hold on HD-94 in Norfolk. His next election is in 2027.
Hernandez first ran for the House of Delegates in 2019 in the Eastern Shore's old District 100, losing to Republican incumbent Robert Bloxom by 3.9 points. He ran again in 2023 in the newly drawn HD-94 and won. In 2025, he expanded his margin against the same Republican opponent Andy Pittman from 11.6 to 22.7 points. He raised over $2.1 million across both campaigns. Not up for re-election until November 2027.
