Census Bureau released its populations estimates: "Southern and Western states are growing so much faster than the rest of the country that several are expected to grab House seats from the Northeast and Midwest when Congress is reapportioned in 2010.
Demographers and political analysts project that Texas and Florida could each gain as many as three House seats. Ohio and New York could lose as many as two seats apiece." Nevada, by the way, grew at a faster rate than any other state for the 19th consecutive year, followed by Arizona, Idaho, Florida and Utah. See this useful chart from USA Today.
The South is just better.
