The Latest: Judge won't immediately toss primary lawsuit
The election was marred by long lines at polling places and complaints by voters who believed they should have been allowed to cast a ballot but weren't on the rolls.
The attorney general is seeking to have the case thrown out on procedural grounds, but Gass didn't give an indication of whether he thought that effort had merit.
The lawsuit alleges Secretary of State Michele Reagan and county recorders mishandled voter registration requests and improperly cut the number of polling places in Maricopa County.
