Mark Halperin at The Page has the McCain ad responding to Romney’s latest attack. McCain makes use of anti-Romney editorial opinion from local press that has been blistering. McCain is banking that the doubts about Romney’s credibility have gained some traction and Romney’s decision to strike first will make the public more receptive to an ad that essentially says: “Romney can’t be trusted.” McCain is aided by New England op-eds plus independent fact checkers whose remarks his campaign is widely circulating that he hopes will help convince voters that he is indeed the straight talker and Romney is not. While Romney is engaged in a two front war in NH and Iowa Huckabee is up with his own ads and encouraged by another poll showing him holding with a 7 pt lead. Meanwhile, Rudy is blanketing the cable news shows to remind voters he’s just the right tough guy in a tough world. And Rudy by the way is spending a whole lot of time in NH between now and the 8th– perhaps hoping that a Romney loss in Iowa and an effective barrage by McCain will leave open the possibility that he can edge up on the NH leaders, make a comeback kid finish and snag some headlines to gain momentum going into Florida.
