There are ways around the lack of severability clause, it’s not unprecedented to uphold parts of it. But without the individual mandate, the guts of Obamacare are pulled out. A+++ There are truly extraneous amendments contained in the obamacare statute that have zero relation to it, i would be truly surprised if they struck all of those down.
They are not reading 2400 pages.
My take is this.
the 5 that will vote to overrule, will take into account that there was a period of unified government, and hence NO political discussion on the merits.
They will strike it down and return it as a Political question to be addressed.
That wont be in the language, but should be the reasoning.
