Ajabu's Campaign initially turned in about 4,700 signatures of which only 1,300 were certified. Ajabu gathered 4,430 more signatures; however, the Marion County Board of Voters Registration rejected all of them (see document below).
Ajabu's campaign performed their own review of the signatures using the Board's database. That review confirmed that 2,418 of the 4,430 signatures were valid for a 7th congressional district candidate.
Are Democrats working to prevent Ajabu from appearing on the November ballot? Since one of the signatures on the document below is from a Democrat Voters Registration board member, it certainly seems so.
