I disagree. I think killing obamacare will make obama supporters depressed and they will stay home on election night.
I don’t think the outcome matters in regards to November anywhere near as much as the response.
If the whole thing is struck down:
Obama has now accomplished nothing domestically; he’s supposedly a constitutional law professor and his major attempt at legislation was unconstitutional. He’s a failure.
OR, the partisan SCOTUS is legislating from the bench and the Left better fight as if their lives depended on it, because it really does.
If the whole thing is upheld:
The SCOTUS isn’t going to bail us out from stupid decisions, the Right has to fight as if our lives depend on it, because they really do.
OR, Obama was vindicated. The Republicans lied about its constitutionality. The Emperor really does have wonderful new robes.
If just the mandate is overturned, we’re left with an undeniable charlie-foxtrot and both sides will be super motivated to be the ones to clean up the mess.
So, pretty much no matter what happens, both sides can spin it to boost their side come November. (And I’m sure you can come up with lots of other arguments that I haven’t). The impact on November will come from who is better prepared to respond to the ruling, not necessarily on the outcome.
