Backers of a proposed referendum on Missouri’s gerrymandered congressional plan believe they have met the minimum number of signatures needed to make the November’s ballot.

Updated data, posted Monday morning by People Not Politicians, the political action committee that organized a referendum petition drive, shows that the petition has at least 129% of the required signatures in the 1st, 2nd, 3rd, 4th and 5th districts. The last district needed to qualify for the ballot was southwest Missouri’s 7th District and 102% of the signatures needed are valid, with more than 6,000 signatures left to be checked.
