I'm afraid you don't understand how this works.  Insurance people are not doctors either.  They use Actuaries to calculate all those things and more. They will figure out what is normal and build around that.  There is zero chance these politicians will do something to make HALF the voters mad.  They might do something which changes how the burden of the worst uninsurable people (both male and female) are covered, but that effect is on 10% of the people for the benefit of the other 90%.  There is no attack on women, period.
