"intervened in cases supporting gun-owners' rights, states’ rights, and the right to religious expression in public places. In one high-profile case, Cruz wrote the brief that persuaded the court to approve a monument of the Ten Commandments outside the state capitol, in Austin. (Abbott argued that case.)
In just over six years, Cruz argued nine cases before the U.S. Supreme Court, more than any other Texas lawyer during this period and more than all but a few lawyers in the country. In addition, he filed dozens of briefs in federal and state appeals courts. In his arguments before the high court, Cruz won five cases and lost four, but that understates the magnitude of his success. The cases he lost were rather minor; in one of them he appeared as a friend of the court. The cases he won had more drama and importance."
That’s were I personally think Cruz’s talent should be used, SCOTUS.
