New Jersey’s registered voters strongly support a constitutional amendment to raise the state’s minimum wage by one dollar and index it to inflation, according to a new Rutgers-Eagleton Poll. The increase from $7.25 to $8.25 an hour will be on the November ballot and is supported by 76 percent of voters. Only 20 percent express opposition. Support is wide, and includes a majority of Republicans who plan to vote for the increase, despite Gov. Chris Christie’s earlier veto of a similar measure.
