"So far, 44 States, or 88 percent of the States, have enacted laws providing that marriage shall consist of a union between a man and a woman. Only 75 percent of the States are required to approve a constitutional amendment"

This quote by Jack Kingston is describing the fact that 44 out of the 50 states in the United States have passed laws that define marital relationship as a union in between a male and a lady. This implies that 88 percent of the states have passed such laws. However, in order for a constitutional change to be passed, 75 percent of the states need to approve it. This suggests that even though a bulk of states have actually passed laws specifying marital relationship as in between a man and a female, it is still not enough to pass a constitutional amendment. This quote is highlighting the trouble of passing a constitutional amendment, even when a bulk of states have already passed laws on the very same issue.
