I actually called Newt's campaign today to ask what they are doing to get the “truth” out besides posting it on Newt.org. Not everyone is on the internet and capable of going to his website to read the disputes of Romney's lies. So they do need to do something to get the message out to the elderly and anyone who is not on the internet and not watching cable TV.
They assured me they have mailers, newspaper ads, phone calls, etc.
But research shows most people still get most of their “news” from TV. So TV ads are still important for a huge segment of the population.
