(AP) - A new poll finds that just over half of New Jersey's voters think U.S. Sen. Bob Menendez should resign from office after being indicted on corruption charges.

The Quinnipiac University Poll released Thursday finds 52 percent of voters want him to step down while 39 percent think he should not.

The Democrat's approval rating also slipped to 35 percent, down from 46 percent in January.

Menendez spokesman Mike Soliman says the senator has been the victim of a "smear campaign" and that the poll takers left out Menendez's side of the story when asking respondents what they think he should do.

The cellphone and landline poll of 1,428 randomly selected New Jersey voters was conducted April 9-14 and has a sampling error of plus or minus 3 percentage points.
