The presidential contest was decisive in Contra Costa County, according to final figures released today by the County Registrar of voters.
President Barack Obama defeated Republican challenger Mitt Romney in every incorporated city.
In total, 442,143 Contra Costa voters cast ballots for president. Of those, 290,824 voted for Obama and 136,517 voted for Romney.
In 2008, Obama received the same strong support in Contra Costa County. The president received 260,238 votes to Republican nominee John McCain's 111,742.
This year, in some cities (Danville and Clayton), Obama had what could only be described as a narrow victory. In others (Richmond and Martinez), the president fairly well trounced his opponent.
As expected, Obama did well in blue collar cities like Martinez (home to Democratic powerhouse George Miller), where he received 11,641 to Romney’s 5,527, with an 80 percent turnout.
In 2008, Obama received 12,921 votes in Martinez compared to 5,625 for McCain.
