Final answer:
In 1998, Texas politicians collaborated with college students to propose a new state constitution, but the effort failed despite being formally presented to the legislature.
Step-by-step explanation:
The event that almost led to the revision of the current Texas Constitution was the initiative taken by two politicians in 1998, who enlisted the help of college students at Angelo State University to draft a completely new constitution for the state of Texas. This proposed constitution was presented to the Texas legislature but ultimately failed to pass. The process, although not resulting in a new constitution, served as a significant learning experience for the students involved.
