I lived in TX for 15 years and always marveled at the power that the good people of Texas have allowed their state government to have. You basically have a Dictatorship as there are no term limits on the Governor or Lt. Governor offices.
Those in power seem to obtain great wealth while in office, (see Rick Perry for an example).
Texas does not allow statewide citizen-initiated ballot measures or referendums. "They" will make the decisions for you as to what they consider appropriate.
Very business friendly environment as there are no state corporate income taxes. That frees up money for generous campaign donations.
