If Virginia voters have forgotten about George Allen's "macaca" gaffe, a labor group is out to remind them.

Workers' Voice, a super PAC with ties to the AFL-CIO, released a series of Internet ads today aimed at highlighting some race-related incidents tied to the Republican.

Allen is trying to win back the U.S. Senate seat he lost six years ago, when he was caught on video calling a young man of Indian descent "macaca." It's a derogatory word that can mean monkey in some countries.

"George Allen kept a noose and a Confederate flag in his office and anyone who would insult the African-American and Latino people of Virginia this way is not fit to hold office," said Eddie Vale, communication director for Workers' Voice. "This is similar to, but even more offensive, than Mitt Romney secretly attacking 47% of all Americans."

The Allen campaign said voters are talking about jobs, the economy and gas prices -- not "old accusations."

"George Allen has apologized and forthrightly addressed these old accusations, but when he is on the campaign trail, he is hearing from Virginia families and small businesses concerned about skyrocketing fuel costs, burdensome regulations and increased taxes that are bringing uncertainty," said Allen spokeswoman Emily Davis.

She noted the ties between the AFL-CIO and Democrat Tim Kaine, Allen's opponent, and their opposition to right-to-work laws "that give Virginia a crucial economic advantage in encouraging investment and attracting new jobs."

Kaine has been sticking to the economy, jobs and Allen's record as governor and senator in the campaign. The Virginia race is one of the hottest in the country and will help determine which party holds power in the Senate. Democrat Jim Webb is retiring.

The ad buy is small (worth $54,000) and targeted to Northern Virginia and Richmond, Workers' Voice says.
