LINCOLN, Neb. (AP) — Organizers of a campaign to reinstate Nebraska’s death penalty say they’re cautiously optimistic they’ll gather enough signatures to place the issue on the 2016 ballot.

Nebraskans for the Death Penalty has less than a month remaining to gather about 58,000 signatures before an August 27th deadline.

The group was launched on June 1st, with heavy financial backing from Governro Pete Ricketts and his father, billionaire TD Ameritrade founder Joe Ricketts.

Spokesman Chris Peterson says the group has collected signatures from all counties except for Sioux County, but declined to release how many have been gathered so far.

Danielle Conrad, who is leading the Nebraskans for Public Safety campaign against the referendum, says her group will prepare a “strong and competitive” campaign if the issue makes it to the ballot.
