Since the SCOTUS has ruled in favor of Obamacare (not entirely unexpected, though one of the names on the positive side of the decision was), the question becomes, 'What now?'
Here's my prediction: This decision won't be as bad as we fear. I predict that without the SCOTUS to run against, there's now a fair-to-middlin' chance that the democrat incumbent in the White House could lose the election, which is a historically rare occurrence. I also think this will lead to 10-15 additional GOP wins in House elections, and one or two wins in the Senate.
All that said, we now have a SCOTUS precedence that the federal government can tax the people in any amount for any reason. That is certainly is a problem.
We'll see how it goes in November.
