SAN DIEGO -- It looks like last month's San Diego mayor's election is headed for a recount.

Unlike the recount last November, this one is not about filling in the bubble next to the candidates' name.

Instead, it's about the accuracy of the voting machines.

An organization called Citizens Audit asked people in 11 precincts to vote a second time as they left their polling place.

They then compared their results to the official results and believe there is something wrong.

They will make their recount request after the official results are certified, probably within the next two weeks.
