Federal appellate judges on Wednesday questioned assertions by attorneys for the state and its Republican Party allies that a new law outlawing “ballot harvesting” does not target minorities. Assistant Attorney General Karen Hartman-Tellez argued that the law, approved earlier this year, is a legitimate — and legal — effort by the Republican-controlled legislature to ensure the integrity of elections. She conceded that making it a felony to collect the ballots of others might result in some inconvenience. But Hartman-Tellez said there was no proof that minorities would be harder hit.
