Neither was the assertion.
What happens to other members of the club? Don't know and in some ways I don't really care. Keeping 25 Prod drivers who might come to an OGM IT category doesn't compensate for the far greater number of current IT drivers that won't be happy. The club isn't offering these disenfranchised prod drivers what they want. Some have asserted that IT as a National class is what they want. I doubt the veracity of that statement and there has been no evidence presented to reject the null hypothesis - IT category, whether National or Regional will keep a disenchanted Prod driver fat and happy.
The circumstantial evidence refutes the position that there is an untapped source of NASA drivers just dieing to race IT if it gets a OGM. NASA's "successful" classes aren't IT by a long stretch. If you want to go down that road, you'll need to suggest that we adopt yet another category - NKO (Nasa knock-off).
