The Democratic Party has shed about 2.1 million registered voters nationwide since the 2020 election, while the Republican Party has added roughly 2.4 million, according to voter-file data compiled by analytics firm L2 and highlighted by The New York Times and CNN. The shift leaves Democrats with a 4.5 million-voter deficit across the 30 states and Washington, D.C., that record party affiliation, narrowing a registration gap that stood near 11 percentage points five years ago to about six points in 2024. Registration losses hit Democratic strongholds such as California as well as battlegrounds including Arizona, Nevada, North Carolina and Pennsylvania. The party’s share of newly registered voters under 45 slid to 48% from 66% in 2018, and its share among men fell to 39% from 49% in 2020. Hispanic support also eroded: Democrats captured only 33% of new Latino registrants in Florida last year, down from 52% in 2020, and 58% in North Carolina, down from 72%. Strategists across the party warn the numbers underscore deeper organizational and messaging problems that surfaced after President Donald Trump’s 2024 victory. Some Democratic operatives fault a strategy that outsourced registration drives to outside groups rather than undertaking door-to-door efforts coordinated by campaigns. With mid-term contests less than a year away, party officials face mounting pressure to rebuild field operations and re-engage younger, male and Hispanic voters who have drifted toward the GOP.
