PRK's Population Composition Myth

I haven't debunked this particular claim from Philip R. Klein in at least three weeks. His confusion is most likely attributable to his ignorance about what actually constitutes a majority-minority county:

The minority community makes up the majority as white flight continues in the county.

From the U.S. Census Bureau 2008 PEP for Jefferson County: 

• White persons not Hispanic: 47.5%
• Black persons:  34.6%
• Hispanic or Latino origin: 14.4%
• Population, percent change, April 1, 2000 to July 1, 2008 -3.6%

We'll revisit when the 2010 Decennial Census is released. As of 2008, 10 percent of all U.S. counties are now majority-minority and another seven percent are close. While the demographics of Jefferson County qualifies it as a majority-minority county, the majority is still white.  This is not what Klein claims.

According to the Census Bureau, Texas is one of four such states. If Klein's fallacious logic had any merit at all, President Obama would have carried the state in the 2008 elections and Republicans wouldn't hold every elected office in the state government.
