Other example would be when a person is inherently believe that he is somehow intellectually inferior and cannot do anything to improve their get. This often lead him to not making any efforts since he believes it pointless, which lead to self-fulfilling his initial opinion about himself.
The answer is: d. republican
Before William Clements took the position as the Elected Governor, Texas' votes were dominated by the Democratic party for around 105 years.
He was popular because he brought in his business acumen to state government, and proposing a clear and sound Government budgeting, military defense, and Program management policies. Texas has been dominated by Republican party ever since he took the position.
