BIG: Public Policy Polling Has Ron Paul In First Place In Iowa

Public Policy Polling, which I consider the best polling organization in the country, now shows Ron Paul in first place:

Newt Gingrich's campaign is rapidly imploding, and Ron Paul has now taken the lead in Iowa. He's at 23% to 20% for Mitt Romney, 14% for Gingrich, 10% each for Rick Santorum, Michele Bachmann, and Rick Perry, 4% for Jon Huntsman, and
2% for Gary Johnson.

Gingrich has now seen a big drop in his Iowa standing two weeks in a row. His share of the vote has gone from 27% to 22% to 14%. And there's been a large drop in his personal favorability numbers as well from +31 (62/31) to +12 (52/40) to now -1 (46/47).
Negative ads over the last few weeks have really chipped away at Gingrich's image as being a strong conservative- now only 36% of voters believe that he has 'strong principles,' while 43% think he does not.
