NumbersUSA, a group that opposes illegal immigration and also advocates for limits on legal immigration, last month released the results of a poll it commissioned from Pulse Opinion Research, a subsidiary of Rasmussen Research. 

The poll asked: "On the issue of illegal immigration, do you favor or oppose mandating that all employers electronically verify the immigration status of their workers?" Seventy-eight percent were in favor, 12 percent were opposed and 9 percent were unsure.
