The Breitbart/Gravis instapoll showed Trump actually gaining support following the debate by a net of three points, despite Clinton winning the debate by five points. The poll oversamples Trump supporters by five points, so Clinton really won the debate by more like ten points. If this is so (tomorrow’s polls will make it clear), we know that the challenger-gains-in-polls effect is not due to the challenger actually winning or losing a debate.

If Trump did, in fact, gain support following the debate (meaning he’ll win Colorado and New Hampshire soon enough), that means Clinton badly failed at Her job and failed to outline a positive message for Her campaign.
