Ten San Jose mayoral candidates filed paperwork with the city clerk before the Friday deadline--all of them Democrats.
The top five candidates are familiar names in the South Bay.
Four of the candidates are current city council members, including Vice Mayor Madison Nguyen. She has been representing District 7.
Councilman Sam Liccardo, a former deputy district attorney, is the top fundraiser so far. And Councilman Pierluigi Oliverio is making police support the cornerstone of his campaign.
Councilwoman Rose Herrera's district has sizable Latino and Asian-American populations.
Also in the top five is former city councilman and current Santa Clara County Supervisor Dave Cortese.
NBC Bay Area Political Analyst Larry Gerston said with a field of 10, the city is likely to see a runoff.
"With so many candidates, it's very unlikely that any one candidate is going to get 50 percent plus one that's required to win outright," Gerston said. "Therefore, the top two will move on to the November finals, the time of the general elections."
In a poll of likely voters, sponsored by several unions, Dave Cortese leads the pack with 19 percent of likely voters, followed by Vice Mayor Madison Nguyen.
Here are the results of the poll:
Dave Cortese -19%
Madison Nguyen -15%
Sam Liccardo - 10%
Pierluigi Oliverio - 8%
Rose Herrera - 6%
Forty percent of the people polled did not choose a candidate.
Gerston said while the methodology of the poll is solid, it was only conducted in English.
