The latest Rasmussen Reports poll has Gingrich with 38% support and a 21% lead over Romney. I make this observation not because politics and whether this is good or bad. It is just as a futurist and predictor, what happens in the US election and with the Republican presidential nomination can effect certain scenarios.
Cain falls to 8% in the latest polling. Cain will make some announcement on the weekend. I predict he will pull out of the race. The Rasmussen polling seems to indicate almost all of the dwindling Cain support will go Gingrich.
Gingrich has a big lead in Iowa and again it will get bigger when Cain pulls out. Ron Paul could end up second.
