George Lakoff said this quote
“ Why didn't the Democrats accomplish more right after the 2006 elections that gave them control of Congress? It wasn't just that they didn't have votes to override a presidential veto or block a filibuster. They didn't use their mandate to substantially change how the public--and the media-- thought about issues. They just tried to be rational, to devise programs to fit people's interests and the polls. Because there was little understanding of the brain, there was no campaign to change brains. Indeed, the very idea of changing brains sounds a little sinister to progressives-- a kind of Frankenstein image comes to mind. It sounds Machiavellian to liberals, like what the Republicans do. But changing minds in any deep way always requires changing brains. Once you understand a bit more about how brains work, you will understand that politics is very much about changing brains-- and that it can be highly moral and not the least bit sinister or underhanded. ”
