Romney is a good bet to win NH, but Gingrich was at 35% nationally a week ago and has fallen to 27% now (RCP avg) -- South Carolina is a full month away and his last 3 polls there are going the wrong way: 42 -> 38 -> 31.
A week is a lifetime in politics. Gingrich picked up a lot of Cain's support but now he's bleeding fast.
You are not helping your case here. In the same time period, Santorum has gone from 3.5% to 3.8% nationally. And two weeks ago he was at 7.7% in Iowa. Now he’s at 7.0%. Not exactly what I would call picking up momentum.
