People , from every state in this nation, go to colleges and / or universities in other states. It doesn't make you , nor anyone else , a " TEXAN ", because you go to a college in the same state that you were born in, or resided in most of your life. What you are promoting, is inbred stupidity ... don't ever leave where you were born / come from, or else, you aren't ... whatever.
BTW, you aren't all that smart / intelligent and you most assuredly are ill informed. You had NO idea where any of the Bush family was born, went to school, live / ed, and I suspect that you know even less about politics, current events, history, and much more. As far as " proving " any point, that you delusionally imagine that you've made, don't fatter yourself. The only thing proved, by our discourse, is that instead of surmising that you don't know what you attempt to talk about, we now know that, for a fact. :-)
Here's my point. Dubya was not born in Texas. Dubya did not go to college in Texas. Therefore, under the rules, Dubya ain't no Texan.
