In my opinion, this appointment indicates a bipartisanship without substance on the part of Obama. Or, at the very least a bipartisanship that is unwilling to share power.
Sure, the Republicans gain a seat in the executive administration, but they lose a far more powerful ability the legislature: The prerogative to block legislation they find egregious. Overall, this is a net loss for Republican power. If the guy takes the appointment, he is looking out for himself, and not the interests of the Republican party.
I have said many times before, I am opposed to a government that is too liberal. While I would be perfectly happy about any Judicial appointments that would sail through, now, I deem the cost too much to bear. I do not think this appointment should happen and I hope the Republicans are able to prevent it somehow.
