2010 Census counting non-citizens for Representation?

The Wall Street Journal has up a provocative article that claims the 2010 census has been set up to explicitly omit any questions of citizenship, and thus inflate census totals for those States with large populations of illegal immigrants. In one example given, California would gain around 10 new Representatives just at the time that citizens are fleeing the State because of economics.

If this is true, quick action is needed to correct the plans for the census. The Constitution is fairly clear that citizenship is a critical factor in calculating representation in Congress, and even small changes in how we count citizens could have significant effect on both the laws we pass and how we select the President.
