I wonder why religious S. Koreans would vote for the D?
That is hard group to analyze because they invaded the East coast with such numbers they tend to stick with their own cliques and language. I see many of their kids who do assimilate wit their peers benefit from their hard work (and yes the immigrants appear to be industrious) , being given expensive cars and playing Rap music and smoking. But they may not vote.
While it may be not directly related/caused by them, but I see Maryland counties go from R to D as they moved in in great numbers.
I have noticed that Rs have not been polling great with Asians. if you see polls to the contrary let me know.
