I don’t generally act based on polls. But they are an informational data point. And the one-on-one matchup polls have been very consistant for some time now. Romney and Santorum have both polled very well against Obama, while Gingrich has consistantly been losing by double-digits to Obama ever since I can remember.
The last time Gingrich actually beat Obama in a one-on-one poll was in November of 2011 (Gingrich +2). He hasn’t been closer than 9% in the RCP average in 2012, and he has been down by more than 10% since January 16th.
In contrast, in 2012 the MOST Santorum has every been behind is 10.3%, and he’s been closer than 8% since his surge in mid-February (I was wrong on my Santorum numbers, it’s currently 7.9% not 8.7%)
What’s your point?
Your statistical fog, won’t matter anyway in another month. The April vote will pretty much settle it.
