Michael Evans has looked at past oral arguments in front of the Court. It turns out that the number of questions asked/statements made by the various Justices is a reasonably predictive of how they will vote on a case before them. In essence, if a Justice asks more questions of a counsel, he opposes the propositions made by that counsel. The counsel at bar in the Obamacare case were Verrelli for Obama on the side of upholding the law and Clement for the 26 States with Cavin for the private business groups that opposed the law on the other hand. Below is a chart of the number of words in questions for the various counsel by each of the Justices. Thomas rarely says anything, ever, but we know he will vote with Alito and Scalia to throw the law out. If form holds true then, the SCOTUS will dump Obamacare by a 5-4 vote. And that is directly in line with the observations of most of the pundits and legal observers that I have read.
