The Sunday Register has a new Iowa poll.

The big news on the Republican side is that Romney leads. On the Democratic side, things look like this:

Edwards 29 percent

Obama 23 percent

Clinton 21 percent

Richardson 10 percent

Biden 3 percent

Kucinich 2 percent

Gravel 1 percent

Dodd less than 1 percent

not sure 11 percent

As with every poll, I think this understates the percentage of undecideds. My best guess is that 30 to 40 percent of the caucus-going Democrats I talk to are undecided.

I am not at all surprised to see Obama in second place, even if his lead on Clinton is within the margin of error. I have long argued that Edwards and Obama would finish ahead of Clinton in Iowa. 

Looks like spending money on tv ads was a smart move for Richardson. It helped that they were unusual and memorable tv ads. They've certainly got a lot of people talking. 

The poll claims a 4.9 percent margin of error. If you want to know more about the methodology, including the wording of the questions asked, click here.
