As a non-Texan I do think that Texas (and California) "could" survive as independent economic countries, whereas most others states, and even some entire regions could NOT. 25,000,000 people is clearly enough people for creating a country.

I will point out though with current Demographic trends Hispanics WILL outnumber Whites in Texas by 2020, and when combined with Blacks (about 12% of the population), the current minorities in that State will greatly outnumber Whites by then.

(per the data above Hispanics are increasing their overall percentage of the population by about .5% per year and Whites are losing a similar amount, .5%, each year ... mainly because the growth rate of Hispanics is running at a rate that is about 4x that of Whites)

If Texas would become independent then by 2025 or 2030 (as young people grow up and become voting adults) it would ethnically be more Hispanic than White even among the adult population (and even if all the illegal aliens were shipped home).

Are those almost screaming for Texas Independence (who I assume to be mostly White) prepared to be a Minority of the population in the country of Texas with Majority of that newer Country being Hispanic? .... or are they just trying to ignore the realities of Demographics believing that what is happening on the demographic front isn't really happening?
