There was context around Biden’s “garbage” remark, too, yet it also did not much matter.
As @hawkstwelve just said, context doesn’t matter so much in political campaigns. If anything you say can be ripped out of context and repeated endlessly by the other side, it will. Been that way for a long time. A good campaigner has to ALWAYS watch what s/he says.
I am curious: What were you doing 20-odd years ago when the Cheneys and the rest of the neocons were stampeding the USA into a war against Iraq based on a pack of lies?
