I know they were born here. Despite some controversy over birthright citizenship, I get that they are legal. Not in dispute here. Where is the misrepresentation that if we had less Hispanic illegal immigrants we'd have less Hispanic population and voters?

California was long a red state. It also had about 90% white voters for a long time. As it has become majority minority, it has gone strongly blue. Look at demographic breakdown of issues and elections and the reason is obvious.

A conservative should be ok with this?
