Oh, he's fired up over the recent SCOTUS rulings; so much so that he wants a Constitutional Amendment that would allow voters to remove activist Justices. And while in general I appreciate Mr. Cruz's candor and his willingness to stand up to the establishment Republicans, his call for an Amendment is entirely backward.
The rulings actually provide Republicans with a much-needed shot in the arm; campaigning just became easier for Republican candidates, as has fundraising. Obamacare is here to stay - and that's an anvil hanging from the neck of Grandma Clinton; Democratics own it.
And as for the ruling on homosexual marriage: as observed here yesterday, the first articles pushing for legalization of polygamy are already emerging. We can expect Republicans to campaign on family values, the shredding of the Constitution, and much more in the coming months. If not for these rulings, Republicans would have had a murkier time of it; they'd have been stumbling around in search of messages that resonate.
Obviously, although they have reason to, Republicans aren't likely to cheer the rulings - at least, not in public.
