Gallup said 76 percent of respondents in a poll taken Nov. 5-6, indicated they would vote to add $1.75 to the current minimum wage of $7.25 per hour.
In a March survey that asked the same question, 71 percent indicated they would vote to raise the minimum wage by the same amount.
Gallup pointed out that the proposal in last Tuesday's election to have the minimum wage in New Jersey raised to $8.25 per hour passed by a 61 percent to 29 percent majority.
"An even greater percentage of Americans would vote for an even higher minimum wage" than that, Gallup said.
Adding the stipulation that the $9 minimum wage would than have increases over time that were tied to inflation diminished its support slightly. Sixty-nine percent of respondents indicated they would support a $9 per hour minimum wage that include a cost of living adjustment stipulation, Gallup said.
Gallup said the survey results came from a random sampling of 1,040 surveys that were part of its Gallup Daily tracking survey.
It can be said with 95 percent certainty that the results of the survey are accurate with margin of error of plus and minus 4 percentage points, Gallup said.
