well Obama's "post-partisan POTUS", lasted about as long as "the most transparent adm", etc. and other crapola Obam either deluded himself into thinking,
or just mouthed off about without thinking.
Obama is a shrewd political animal - he knows how to play the political blame game. Is it called for? Some of it yes; some of it is just deflection.
I'm more domestically liberal then not, but I do have a problem with the regulatory agencies essentially creating law.
Oh it's all constitutional -at least for now-

The rise of the 4th branch, and it's not a good idea; to just let regualtory agencies (EPA and such) write what is law in practice.
They do not self-limit, they constantly expand ther roles.
Obama would argue this is how to bypass the "obstructionists", and in the short term yhers it is.
Long term it is anti-constitutional,if not wholly un-constitutional.
Obama is the executive, and it's logical for an executive to glom up powers.
I just do not like this rise of executive powers, but hey..Congress is such a mess I suppose things gotta get done.
I do think you vastly overplay the race factor here -i'm sure it exists, but is not the nmajority reason to oppose Obama (IMHO)
