Hahaha. I cant wait for the repubs to tell americans that insurance will begin denying on pre-existing conditions again...(Did you know they have entire departments designed to find ANYTHING in your past or present to deny you)
You mean just like when you apply for a credit card or loan, they check your credit history ?
or when you apply for auto insurance they check your driving record ?
And now any children living at home from 19-26yrs old are not covered.
And it'll be great when they cancel your policy just because you filed a claim. Bring it on..... 
Prior to Obamacare they could stay on till 23 as long as they were in school. Since when is a 25 yr old (not going to school) considered a "child" ?
It seems you understand Insurance about as much as you do our tax code.
