Support for Bob Menendez has cratered since his indictment, with approval ratings for the three-term United States Senator now at a jaw-dropping 8%-72%, according to a new Stockton University Poll released today.

More than seven in ten New Jerseyans (71%) think Menendez should resign from the U.S. Senate after he was indicted on bribery and conspiracy charges, and just 8% said he should remain in office; 80% of state residents are aware of the criminal charges filed against the senior senator from New Jersey.

Menendez’s approvals are one point better than Illinois Gov. Rod Blagojevich, who was at 7% following his indictment for trying to sell Barack Obama’s U.S. Senate seat in 2008.

[When 71% of your constituents not only won’t support you but want you to resign your seat mid-term, that’s what we call a “hint” or a “clue.” Perhaps Menendez should use a gold bar and buy one or the other. His fellow Democrats aren’t taking any damage yet in the Garden State, but they won’t be anxious to wait and see whether that buffer lasts. — Ed]
