According to the CBS News 2016 Battleground Tracker conducted May 31 through June 3, Clinton holds a solid lead over Sanders, 61 percent to 34 percent with a 5.4 percent margin of error.

Voters were also asked about hypothetical head-to-head matchups between the two Democratic candidates and likely Republican nominee Donald Trump.

Both Democratic candidates hold double-digit leads over Trump with Sanders faring slightly better, at 52 percent to 34 percent, than Clinton, at 49 percent to 34 percent.

New Jersey is one of six contests that will be held on Tuesday.

On Saturday, Sanders predicted that July's Democratic convention in Philadelphia will be contested.
