Netanyahu has remained the caretaker prime minister through the repeat elections. The latest comes two weeks before he is set to go on trial on charges of bribery, fraud and breach of trust.
Gantz in his campaign said Netanyahu is plagued by scandal, while Netanyahu said he is best qualified to lead the country at this time.
Once the election results are in, President Reuben Rivlin will select the candidate he thinks has the best chance to form a coalition and give them up to six weeks to do so. If that candidate fails, another would then have 28 days to form their own coalition.
