Takes one back to Nixon, who said he "accepted the responsibility" for Watergate. When asked if that meant the blame, he wouldn't answer.
People ask why on earth Clinton would accept any liability; why, in fact, she would want to help the guy who used racist tactics to defeat her in 2008. Simple. For her, Obama MUST win. Obama loses and Romney is probably in the White House until 2021, by which time she will be too old, even more haggard-looking, and yesterday's news, having been out of government office since 2013.
