Democrats will almost certainly outnumber Republicans in the seventh congressional district by April.
In February, the district added 1,009 Democrats to its rolls, while Republican registration fell by 56.
The changes bring the GOP registration edge down to 382. It was 1,447 at the start of February.
Republicans outnumbered Democrats there 157,536 to 164,245 on election day in 2018, when Rep. Tom Malinowski mounted a successful bid to oust Rep. Leonard Lance.
When the new district was drawn following the 2010 census, the 7th had 29,997 more Republicans than Democrats.
The first-term congressman faces a challenge from Senate Minority Leader Tom Kean.
Unaffiliated, or independent, voters still account for the lion’s share of the district’s registration figures.
The district has 219,039 voters registered without party affiliation, while there are 168,125 Democrats and 168,507 Republicans there.
