Yes, I think Republicans knew that immediately. The man -- you may disagree with him, but he's the head of state. He's our president. He's all of our presidents. And there's a certain matter of decorum.Point of information: South Korea doesn't have a parliamentary system either, but the utter lack of decorum (at times) is spot on. He should have thrown Taiwan in there for good measure.
This is not Britain. This is not Italy. This is not Japan or Korea. We do not have a parliamentary system where it's OK to shout at the leader because he's a head of state as well as the head of the government.
But there's been this broad corrosion over many years in the way people talk in private, and then so suddenly he behaved in a way that normally there would be just so many unconscious barriers -- you would never scream out "You lie!" to a president right there in that room. But those barriers have been eroded. He went further than anybody has gone before or at least recently at least...So in the end, was it worth it? He got in his dig that President Obama was lying about not covering illegal aliens (which, eventually, someone may have to decide do, if for no reason than to curb the financial costs and structural strain on emergency rooms), but at what cost to his own cause?
