[U]nder H.B. 530, a law passed this spring by the Republican-controlled State Legislature …. paid ballot collection is now banned….

The ballot collection law is part of a nationwide push by Republican state legislators to rewrite election rules, and is similar to an Arizona law that the Supreme Court upheld on Thursday. In Montana — where Gov. Greg Gianforte, a Republican, was elected in November to replace Steve Bullock, a Democrat who had held veto power for eight years — the effects of that and a separate law eliminating same-day voter registration are likely to fall heavily on Native Americans, who make up about 7 percent of the state’s population.
