Yesterday the Republican Party of Montana announced that it was abandoning its plans to challenge the voting eligibility of at least 6,000 residents of that state-mostly in democratic strongholds-who had filed change-of-address cards with the U.S. Postal Service. In a letter sent to election officials in seven counties, state GOP executive director Jacob Eaton withdrew the party's challenges and said they would be issuing no more. Several hundred letters requesting that individuals confirm their correct addresses had already gone out from overworked election offices before the GOP withdrew its challenge.
