In what is I think both a humble move and a politically savvy one, Obama addresses the "bitter" comment head-on and explains his admittedly "boneheaded" comment:
"How it was interpreted in the press was Obama talking to a bunch of wine-sipping San Francisco liberals with an anthropological view toward white working-class voters," Obama told the Times. "And I was actually making the reverse point, clumsily, which is that these voters have a right to be frustrated because they've been ignored. And because Democrats haven't met them halfway on cultural issues, we've not been able to communicate to them effectively an economic agenda that would help broaden our coalition."
This one quip, among probably thousands Obama has made in this long ass campaign, has come back to haunt Obama again and again and has been used to paint him as an out-of-step liberal with contempt for working class Americans. In an attempt to finally close the deal with these guys, who made up a large percentage of Hillary Clinton's supporters, Obama takes responsibility and looks to mend the fence.
