I kind of look at it as the girls made a load of money feeding the hate-filled liberals who feels their miserable lives are vindicated by any sordid tale they can scrounge up on Sarah or her children. All Sarah needs to do is say "Bristol is an adult and has her own life to live" and that settles the matter, IMHO. Ronald Reagan had controversial children, too. Didn't impact his effectiveness as a leader/conservative.
In the end, Bristol's doing just fine.
And she's not my problem via blood nor the tax dollars the feds have leeched from me.
