Democrats have gained voters in New Jersey’s most competitive congressional districts.
The 3rd, where Rep. Andy Kim (D-Moorestown) is seeking re-election in a district that hasn’t re-elected a Democratic congressman since the 1852, there are now 14,910 more Democrats than Republicans. Kim narrowly unseated two-term Rep. Tom MacArthur (R-Toms River) in the 2018 mid-term elections.
When the Burlington-Ocean district was drawn in 2011, the Democratic registration gap was 8,863. Republican Jon Runyan (R-Moorestown) had defeated freshman Rep. John Adler (D-Cherry Hill) in the previous election, and the redistricting commission had removed the Democratic stronghold of Cherry Hill when creating the new district.
There are now 4,069 more Democrats than Republicans in the 7th district, where freshman Rep. Tom Malinowski (D-Ringoes) faces Senate Minority Leader Thomas Kean, Jr. (R-Westfield).
Republicans lost their registration advantage earlier this year. When the district was drawn after the 2010 census, the 7th had 29,997 more Republicans than Democrats. Malinowski became the first Democrat to win the district since 1954 when he took out five-term Rep. Leonard Lance (R-Clinton Township) two years ago.
Democrats are trying to win back the 2nd district seat they flipped in 2018 and lost in 2019 when Rep. Jeff Van Drew (R-Dennis) switched parties. The district now has 19,365 more Democrats than Republicans, up from 16,251 last month.
Two other longtime Republican seats flipped by Democrats in recent years are also becoming increasingly more Democratic.
The 11th district had 24,176 more Republicans than Democrats in 2012; now there are 1,179 more Democrats. The 5th has 13,303 more Democrats than Republicans; in 2012, the GOP registration edge as 13,085.
Rep. Mikie Sherrill (D-Montclair) ended a 34-year Republican winning streak in NJ-11 in 2018, and Rep. Josh Gottheimer (D-Wyckoff) defeated a seven-term incumbent in NJ-5, which hadn’t elected a Democratic congressman since 1978.
One district has become more Republican over the last decade.
In NJ-4, where Rep. Christopher Smith (R-Hamilton) is seeing a record-breaking 21st term, has seen his district go from a GOP edge of 12,193 in 2012 to 22,296 now.
