In Tuesday's three-way race primary race for the two slots on the November ballot, and were the overwhelming winners.
Tuesday night/early Wednesday morning's unofficial vote, with 99.8 percent of precincts reporting, showed Liu with 51.7 percent of the vote and Gonzales with just over 42.9 percent of the vote. Upland resident and Democrat, Ameenah Fuller, came in third with 5.4 percent of the vote.
Liu, the incumbent State Senator in the existing 21st District, which includes San Marino, was running in a very new looking district, with Pasadena-area cities combined with foothill cities in East Los Angeles County.
Liu, a La Cañada Flintridge resident, has served one term in State Senate and previously served in the California Assembly.
Gonzales, 35, a first-time candidate, lives in Pasadena. He graduated from Pitzer College and is currently the Director of Public Affairs and Government Relations for Vons/Safeway.
Gonzales told Patch early Wednesday morning that he felt his percentage was a "very good showing," particularly in a district with more registered Democrats. He said he believes he can win over non-Republican voters in November.
"I believe that what it comes down to is that everyone, whether Democrat or Republican, is looking for solutions," Gonzales said.
Liu could not be reached for comment Tuesday evening.
