Steve Schmidt, the chief campaign adviser of John McCain in 2008, stated that Romney's attack on the Obama administration immediately following the killing of the US Ambassador in Libya, was a "big mistake." That's the consensus of most Republicans and Dems and media talking heads, other than Limbaugh who is of course on another planet, therefore having a unique viewpoint.
There's an additional problem with Romney's press release and public yammering about the "disgraceful" statement issued from the US Embassy in Cairo in response to the demonstrations against it. The timeline is all wrong. The statement was issued six hours before the demonstrations started- the statement was clearly intended as a desperate local effort to head off the violent demonstrations that were stimulated by the anti-Muslim youtube video pushed by Pastor Terry Jones, not as a RESPONSE to the demonstrations which had not yet happened. So Romney was factually wrong, as well as politically lacking in patriotism and civility at a time of mourning for American state department staff.
Romney is correct- something is indeed disgraceful. But it's not Obama's conduct. It's Romney's. People notice stuff like this, Mitt. What were you thinking? Now that we know what actually happened, who died, and what the order of events was, try again. Do you suggest sending in the drones and marines and gathering information from Libyan sources before making a strike against the Al Qaeda team that pretended to be "protesters" before carrying out their assassination? No, wait a minute, Obama is already doing all that. Let's see, do you suggest we drop a nuke? No wait a minute, that's what most of the right wingers on Gather are suggesting. You're not that stupid, are you Mitt?
