Interesting to see if Rasmussen has stayed with likely republican voters or if he has switched to just likely voters or registered voters
Per the Rassmussen site:
The survey of 750 Likely Iowa Republican Caucus Participants was conducted on December 13, 2011 by Rasmussen Reports.
This is obviously a skewed poll. Rasmussen has been known to get it completely wrong countless times.
For Gingrich to go from over 35%, to being down over 15 points in one day, there is something totally wrong with the poll.
Rasmussen also has his own agenda and he uses it in the early polling season, then tightens it up when his reputation is at stake. His polling method is also rather flawed compared to others.
I say, if this trend continues for another 2 weeks, from all the polls, then there is a problem for Newt.
