Re: Elections 2012 -- Carrion My Wayward Son!
This was essentially the point His Panderness made when announcing that his position on gay marriage had "evolved."
Romney's intelligence and defense advisors are drawn from the same ideology as Bush's, so I think the tendency for all other things to be subservient to their ideology would be asserted very strongly (they aren't coy about this; their foundational principle is that the West, Israel, and America face an existential threat so anything they do is justified).
Note also that the leading proponents of executive power on the Court were appointed by Republicans. The best security for limited government is divided government, but neither party has shown any compunction about trying to push the branch they control at a given time to obtain their ends. Romney comes out of a corporate environment in which there is no democracy, the Decider in Chief says jump and everybody else says how high. That's not a mentality conducive to preserving Constitutional protections designed to thwart power. Even if Romney had respect for the Constitution, and I don't think there's any compelling reason to believe he does, like all business leaders he would find checks and balances to be inefficient and frustrating.
I think it's mostly a wash. We have come to a pass where neither party (and apparently neither side of the political debate) has much respect for the Constitution when it impedes them, and that's the only time actions matter. The right talks a good game, but it's been decades since they respected a principle of law that opposed their agenda. They've been spun up to believe that anything that goes against them is by definition illegitimate. That's the opposite of rule of law.
The other thing about Romney, touched on below, is his extraordinary weakness. The pressures that will be exerted upon him by his ideologically extreme advisors will be severe, and, just as with Dubya, the man does not have the fortitude to withstand them. We see this already with his Gumby act on the campaign trail. In office he will always be suspected by the far right, and thus he will always be bending over to appease them to void an attack from the right flank in 2016.
