Over at Century of the Common Iowan, noneed4thneed put up a link to the latest Rasmussen poll of Iowa. Holy cow–Obama beats McCain here 46 percent to 42 percent, but Hillary loses to McCain 51 percent to 36 percent. McCain has hardly ever campaigned here and finished fourth in the Republican caucuses. Noneed4thneed noted that Rasmussen found

McCain leads Clinton by a two-to-one margin among unaffiliated voters. However, Obama leads McCain 46% to 37% among those same voters.

The latest round of Survey USA polls had a similar finding (sorry, no link). Obama and Hillary look poised to win a comparable number of electoral votes against McCain, but they do it in different ways. Obama was ahead in Iowa against McCain, but Hillary was trailing the Republican. Assuming Obama is the Democratic nominee, I have to believe he would be heavily favored to win Iowa. Rasmussen's poll may show his lead within the margin of error, but Obama has a huge volunteer army to draw on here from the caucuses, while McCain didn't build any kind of organization in Iowa.
