ARG, which has shown Clinton leading in Iowa all year, released a new poll today with similar findings. Details and a spirited discussion of this poll can be found over at MyDD. Here are the key findings:

Clinton 30 (down from 32 in last ARG poll)

Edwards 21 (down from 29 in last ARG poll)

Obama 15 (up from 13 in last ARG poll)

Richardson 13 (up from 5 in last ARG poll)

These numbers just don't ring true to me. I don't believe Clinton leads Edwards in Iowa, and certainly not by that kind of a margin. All year ARG has had Clinton around 30 percent in Iowa, and I can't remember any other pollster finding her with support that high.

ARG's new numbers for Republicans in Iowa are also at odds with recent polling by other firms. ARG finds:

Giuliani 22

Romney 21

McCain 17

Undecided 15

Fred Thompson 13

Gingrich 4

all others 2 percent or less 

What do other people think about this poll?

I guess when other firms release their results we'll find out which is the outlier: ARG or the latest KCCI Iowa poll conducted by Research 2000.
