Turnout on Tuesday was the highest it's been in 67 years.
With 99 percent of the votes in, 35 percent of eligible registered voters cast ballots. That's the most since 1940, when 41 percent voted in a state primary.
Political watchers say the competitiveness of the races drew people to the polls. The decision to move up the primary from June to February also heightened participation.
The highest turnout for any primary in New Jersey was in 1928, when 54 percent of registered voters cast ballots.
The last presidential primary, in 2004, only attracted 9 percent of registered voters.
