pre-existing conditions, the people who are more expensive to treat, will do what it takes. they'll stick around for the extra 25 times to check but the younger people, the healthy people that the white house is relying on to make this system work, they may be less inclined to say, it didn't work the first second or 15th try, i'll come around for a 16th. that's a really concern for the equation that goes into making this system process. >> a good point. those young people are critical to this entire system working. i want to turn to new jersey state politics. something big that happened there today. governor chris christie stopped his appeal of the gay marriage law just hours after it went into effect. so chris cillizza to you, what is the significance of the fact that he's backing away? >> well, so it's interesting, kristen. i think he had fought this all the way, pretty aggressively, but i think this is an acknowledgment by chris christie that charging at political windmills which he believes continuing to fight this law is is pointless. and that nothing is to be gained
