It appears that the Information Age, which has just started taking effect this election season, has created something which is confounding the Left. For a long time the Left could start a smear campaign, or push a piece of propaganda, and with the help of media they influenced public opinion. Now, the smear campaigns and propaganda appear to work for a short time, then once information is put forth to refute the smear campaign and propaganda, there's a shift in public opinion, and the Left is taking it on the chin over and over.
The most recent example is the Democrat/media manufactured War on Women. This has backfired on the Left, and what should have been a 24 story regarding Hilary Rosen's comment disparaging Ann Romney for being a stay at home mom is now becoming a prolonged backlash against those who think smearing and lying are substitutes for intellectual content.
