According to the article, leaks have happened only a couple of times.
But, this time, there are 2 bona fide Obamaphiles that shouldnt even be there, sitting in on the judgement.
Kagan will be hot-linked to the White House.
One thing the article does not mention is that the court may desire for a number of reasons to announce this decision as soon as they can get the opinions written. Some of those reasons are:
1. The further away from the elections they can make it the less political impact it may have. I think Justice Roberts is trying to keep the court out of politics as much as possible.
2. Every day that goes by, the more this law is implemented. If it is to be overturned, sooner is better than later.
3. Congress may need to act if the entire law is overturned and the sooner before the election, the more likely Congress will be able to summon the political will to act.
