It's more likely because you live in Texas. Texas is still very much in the pro-Bush, pro-neocon stance on the world.
The coasts are very polar than your bible belt you live in, and the Midwest has been a dying ground for conservatives over the past 4 years. Texas...is a different story.
Your environment dilutes how the rest of the country views the world. Your anti-tax and anti-government ideals don't mesh in with the nation who is adamant about receiving universal health care to the point republican front runners like Mitt Romney & Mike Huckabee are even talking about it.
State and local government are growing less and less influential and important in the nations eyes. People used to care about local elections to a certain extent, that is shrinking. You live in Texas so you do not see this. The national government, partially thanks to the divisive war is all people talk about.
Michigan is going under a horrible economic recession, did the voters try to make change on the local level? No. They blamed Bush rather than our governor for our problems (incorrectly I must add, MI's problems are not to be laid at Bush's feet).
But lets get on track shall we?
Perhaps the Oprah insanity this weekend wasn't as important as originally thought:
Key finding: "While 97% of likely Democratic Primary voters were aware that Oprah Winfrey had endorsed Obama, just 7% said the endorsement would make them support Obama, while 88 percent said it would not. When the same voters were asked whose endorsement was worth more, 56 percent said Bill Clinton’s, while 19% said Winfrey’s."
