There are far fewer "rich" liberals in the US than this forum likes to believe, and there are without a doubt more rich conservatives. This idea that the Democratic Party is 50% minorities and 50% rich PhD cosmopolitans who play hero and look out for said minorities' interests is ... well, it's funny.
CA is a state run for and by the wealthy liberal elites.
Yet its most affluent county (Orange) is a GOP stronghold. There's not a blue state in the Union that Democrats have these mythical "liberal elites" to thank for their margins of victory.
Have you heard of the bay area? The poorest county in the bay area has the same median income as Orange County.
The bay area is very wealthy if you ignore cost of living.
