Why don't the Dem strategists go after the Latino vote? In CA 50, 20% are Latino. That might be enough to make a difference. Clearly, they are a networked and powerful group. Its annoying they are not participating in a bigger way.
Don't make the mistake that the population demographics for the 50th District match the demographics of registered voters. They do not match up! Plus, what makes you think that the Busby campaign hasn't done serious outreach to latino Dems and latino voters in general?
