"Harry Reid - he votes to give special tax breaks to illegal aliens and to give illegal's Social Security benefits even for the time they were here illegally," the ad's narrator says.
The 30-second commercial also slams the powerful Democrat for his opposition to Arizona's controversial immigration law. Reid has been a critic of the law since Arizona Gov. Jan Brewer signed it earlier this year. A federal judge blocked some of the law's strictest measures in July, hours before they were scheduled to take effect.
"Harry Reid's support for amnesty and his opposition to Arizona's immigration law stands in direct contrast to what the voters of Nevada want," Angle campaign spokesman Jarrod Agen told CNN.
According to a Mason Dixon Polling and Research survey for the Las Vegas Review-Journal and 8NewsNow out Sunday, 46 percent of likely Nevada voters back Reid, with 44 percent supporting Angle. Reid's two-point advantage is well within the survey's sampling error. Six percent are undecided and three percent say they are backing neither candidate.
Angle's ad will air statewide for about a week, Agen said.
