John B. Anderson today accused President Carter's reelection committee of stooping to a "new low level" of "dirty tricks" for broadcasting ads on black radio stations alleging that the Illinois congressman voted against civil rights legislation.

The independent presidential candidate told a news conference here that the ads, narrated by former baseball great Henry Aaron and aired by radio stations in Chicago and Detroit, incorrectly said he voted against the 1964 Civil Rights Act and the 1965 Voting Rights Act.

"This is a deliberate misrepresentation, a gross distortion of my voting record and position," Anderson angrily declared. "It is in short an undisguised lie and a reprehensible attempt on the part of the president and his campaign to scare black voters."

Anderson, making his final campaign stop in New England before Election Day, called on Carter to "stop running ads that are false and scurrilous and let people decide the election on the basis of the issues."

He also charged that as a state senator, Carter voted in favor of a measure that would have exempted Georgia from provisions of the 1964 Civil Rights Act.

Anderson's attack was the latest in a series of accusations of dirty campaign tactics against the Carter reelection committee dating back to the early summer.
