caucus goers say gingrich would be acceptable as the republican nominee. a full 35% call him unacceptable. millions of dollars in negative tv ads targeting him and played a major role in the erosion of his support. a new analysis of the campaign group reports that since december 1st 45% of all advertising in iowa have been negative ads aimed at newt gingrich. think about that. only 20% have been negative ads targeting somebody else or even mitt romney. it s easy to explain what happened to newt. what s interesting here is newt s fall is different from the perry fall or the herman cain fall. it wasn t based on a scandal. it wasn t based on a debate oops moment. it was an old fashioned, what the romney campaign might call a voter education campaign but it was theç fact that newt let it all go unresponded to. the only good news for newt is there s already a person at the bottom of the cliff. he s falling down. and her name is michele bachmann.
