That's not exactly true.
Only if mommy and daddy can afford to keep adult kiddo on their policy. Many can't afford to do that.
Only if mommy and daddy want to keep adult kiddo on their policy and believe an adult kiddo up to age 26 should still be supported by mommy and daddy. Not everyone believes in that either.
So, no, they are not "automatically covered".
“Only if mommy and daddy want to keep adult kiddo on their policy and believe an adult kiddo up to age 26 should still be supported by mommy and daddy.”
Sounds like just one more thing Obama will have to decree to make an adjustment to this mess.
