Yes, his point is valid.
But rules are rules. As conservatives, we think they should abide by them. There is no rule about the drivers weight. End of story. If they want to make rules like that for next season, so be it.
But you cannot change the rules in midstream. We didn't want it in Florida elections, and this is no different in principle.
I was only making the point that 100 pounds is a very significant amount of weight over a 500 mile race, when the total car weight is about 1400 lbs. Race teams literally spend millions of dollars trying to squeeze just a few pounds out of a car's weight.
