Whoa Santorum takes a big lead

In a new Public Policy Polling (PPP) poll, Rick Santorum has opened up a national lead of 15 points.  

Santorum--38

Romney--23

Gingrich--17

Paul--13

No one is even close to a 50 percent majority, but Santorum has almost as much backing as Romney and Gingrich combined.  Looks like a tidal wave which began in Minn-Mo-Co has swept across the country.

For now.
