Far more Democrats than Republicans are requesting mail ballots in key battleground states, including voters who didn’t participate in 2016.

Democrats are amassing an enormous lead in early voting, alarming Republicans who worry they’ll need to orchestrate a huge Election Day turnout during a deadly coronavirus outbreak to answer the surge.

The Democratic dominance spreads across an array of battleground states, according to absentee ballot request data compiled by state election authorities and analyzed by Democratic and Republican data experts. In North Carolina and Pennsylvania, Democrats have a roughly three-to-one advantage over Republicans in absentee ballot requests. In Florida — a must-win for President Donald Trump — the Democratic lead stands at more than 700,000 ballot requests, while the party also leads in New Hampshire, Ohio and Iowa.

Even more concerning for Republicans, Democrats who didn’t vote in 2016 are requesting 2020 ballots at higher rates than their GOP counterparts. The most striking example is Pennsylvania, where nearly 175,000 Democrats who sat out the last race have requested ballots, more than double the number of Republicans, according to an analysis of voter rolls by the Democratic firm TargetSmart.
