most people have moved on from the tragedy [the Benghazi attacks], considering [Hillary Clinton] accepted the blame for it a year and a half ago. It's not even clear what they want out of continually harping on this other than simply smearing her name.
Let's take it as a given that "What difference, at this point, does it make?" counts as claiming to accept blame for something. How does that work, exactly?
Let's use a concrete example. President Obama used drugs, primarily marijuana and cocaine, from his late teens into roughly his late twenties. My source for this is Dreams From My Father, his autobiography. The book came out about 15 years before his Presidential campaign started, and he's answered questions about it throughout his political career. His answers have largely been, "It was stupid. Pay attention in class and don't do drugs." Anyone who was going to vote against him because he used drugs had all the information to do so, straight from the horse's mouth. That's what taking responsibility for something means.
If Hillary Clinton is legitimately culpable for the lack of security at the compound in Benghazi, then her negligence led to the death of four Americans in a terrorist attack. According to you, Clinton has already admitted this. Being responsible, through negligence, for the deaths of four Americans is a legitimate campaign issue, and the Clinton campaign (and you) should be prepared for Benghazi to be held against her throughout the campaign. That's what taking responsibility for something means.
Hillary Clinton hasn't, in fact, admitted that she is responsible. Democrat hacks are STILL pretending the Youtube video spurred a demonstration that Clinton couldn't have forseen. (Eleanor Clift made this claim on The McLaughlin Group on Sunday.) The genesis of this claim is a set of talking points put out by the State Department (led, at the time, by Hillary Clinton) to conceal the issue until after the 2012 election. The coverup, is a separate issue that Clinton is responsible for.
Right now, it looks like Hillary Clinton was legitimately negligent in preparing for the Benghazi attack AND that she led a coverup of the attack to benefit her party on the eve of a Presidential election. We don't know, largely because the Democrats have been stonewalling on this since September 13th, 2012. The American people deserve to know what happened, and that goes double if we're being asked to vote for Clinton for President.
