Here are some other breakdowns for CA 45: They have well above the national average of foreign born people living there at 35% or higher - especially since the rise in illegals this last year. The national average is about 13%. Of this group, they have a high number of illegals that is speculated to be a large chunk of CA's illegal population. No surprise since it is fairly close to the border. The number of registered voters for that district is not available and to figure it out requires taking other stats from the state totals and try to calculate it. Suffice it to say, it is a good district to rally the illegal ballot vote.
