Semore said he wants to see Lantigua leave office as soon as possible.
"He was a mistake," he said. "He has done nothing good for the city."
Semore believes the Latino population in the city will be the determining factor in this election.
"They seem to be divided so it will be interesting what happens tonight," he said. "Those are the votes that are going to make or break someone."
Four of Lantigua's challengers are Latinos.
