Republican incumbent U.S. Rep. Tom MacArthur is barely edging out Democratic challenger Andy Kim in an extremely close 3rd Congressional District race in New Jersey, according to a Stockton University poll released today.

Health care and opposition to President Donald Trump and the Republican Congress appear to be the issues propelling Kim to a statistical tie in a district that MacArthur won by 20 percentage points in 2016. The poll of 546 adult likely voters finds MacArthur ahead with 47 percent to 45 percent for Kim, including voters who lean toward one candidate or the other. Eight percent are undecided or not selecting the two main candidates.
