In the words of Paul Krugman,
What Romney did in the debate ... was, at best, to play a word game with voters, pretending to offer something substantive for the uninsured while actually offering nothing. For all practical purposes, he simply lied about what his policy proposals would do.
Andrew Sullivan writes:
If the lies and propaganda of the last four years work even after Obama had managed to fight back solidly against them to get a clear and solid lead in critical states, then reality-based government is over in this country again. We're back to Bush-Cheney, but more extreme. We have to find a way to avoid that.
The Obama campaign has a series of videos exposing Romney's dishonesty.
