New Jersey Gov. Chris Christie and President Barack Obama share something in common: only 43 percent of New Jersey voters approve of the job they’re doing, according to a Stockton Polling Institute poll released Friday. Fifty-six percent rated Christie’s performance as fair or poor, and 57 percent rated Obama’s performance as fair or poor. Levels of support for two proposed Constitutional amendments on the New Jersey ballot remain consistent with two earlier Stockton Polls this fall. Seventy-eight percent support a proposal to allow judges to deny bail to defendants they think are likely to flee or pose a threat to the community. Fifteen percent oppose it, and 7 percent are unsure. Another proposed Constitutional amendment would increase the percentage of the existing Corporation Business Tax that is dedicated to environmental programs from 4 percent to 6 percent on July 1, 2019. Fifty-nine percent support it, up from 55 percent in an Oct. 9 poll. Thirty-five percent oppose it, and 6 percent are unsure.
