I think that’s a fair interpretation, but it’s not the only one.
An alternate could be that those gymnastics specifically and directly condemn the ACA, and that further, Roberts aim was for an election turned out like the one this past Tuesday. Elections have consequences.
I don’t particularly have faith in the latter one, but it is at least plausible.
I have long thought that Roberts was giving the Democrats the rope to hang themselves. Too many of his other decisions were right down the Constitutional line.
