3) Meanwhile, what's the deal with the U.S. Chamber of Commerce's latest TV ads? First, they spell Democratic Sen. Jon Tester's first name wrong in a Montana spot, and now Democrats in Ohio are accusing the group of doctoring a photo of Mandel's Democratic opponent, Sen. Sherrod Brown -- a charge a spokesman for the Chamber would not confirm or deny. 2) How's this for a confidence check: "I'm going to be the nominee. It's very hard not to look at the recent polls and think that the odds are very high I'm going to be the nominee," former Speaker Newt Gingrich told ABC News. On Saturday night, the full results of a Selzer & Co. Iowa poll will be released and it will be interesting to see where Gingrich stands in the survey, in which Herman Cain's support has plummeted, dropping into the single digits. 1) Despite Cain's drop in the polls and the uncertainty surrounding the recent rise of Gingrich, some Republicans still are not quite ready to hand Mitt Romney the nomination. On A1 of today's New York Times appears a story about the high number of Republican leaders who are torn between getting behind Romney and waiting to see how/if Gingrich or somebody else can make a move. The money graf: "The desire to defeat President Obama is high, but a vast majority of Republican governors, members of Congress and other party elders are content for now to watch from the sidelines, undercutting Mr. Romney's effort to create an air of inevitability and reflecting broader indecision among conservatives even as the time to choose draws close."
