The air war is in full effect in the battleground CD2 Democratic Primary, where Amy Kennedy and Brigid Harrison are battling for their party’s nomination to take on incumbent U.S. Rep. Jeff Van Drew (R-2).

It’s ugly, of course.

Team Harrison criticizes Kennedy for her linkage to a super PAC funded by her husband and for Kennedy’s ties to scrappy Atlantic City operator Craig Callaway.
