New Jersey has been consistently blue in every election since 1992, and usually by quite large, double-digit margins. Hillary Clinton beat Trump by 13 points, or half a million votes.
Registration and turnout isn’t one of New Jersey’s strong points—in the 2016 election, only 60% of voting age residents were registered to vote. According to the October report on voter registration, an additional 251,556 people have registered to vote since January. Since the 2016 election, they’ve had 546,910 more voters, so almost half of that growth in registration has happened just this year.
Another promising sign about turnout—as of today, over 920,000 ballots have already been submitted in New Jersey. That’s a 15% turnout, 3 weeks before Election Day!
