As this is written, the final numbers are not in, but the results of the Iowa precinct caucuses are clear. Two candidates that almost no one in the country had heard of four years ago -- Democratic Sen. Barack Obama and Republican Mike Huckabee -- have emerged victorious. And by mighty impressive margins, particularly so if you factor in turnout.
The Iowa Democratic Party estimated Democratic turnout at 220,000, nearly double the 124,000 recorded in 2004. The Republican turnout appears to have increased from 87,666 in the last contest in 2000 to something like 114,000. That would be impressive, except that it puts Republican turnout at about half the Democratic level, in a state that was split just about evenly between the two parties in the past two presidential elections.
The Des Moines Register was criticized for its poll last week that projected a substantial boost in caucus-goers by self-identified independents. But that poll seems to have been pretty much spot on. Turnout had a big hand in Obama's victory, as he carried young voters by an overwhelming margin and led Sen. Hillary Clinton among all voters under 60. He also seemed to lead among well-educated and upscale voters.
Iowa Democrats' method of scoring the results by "state convention delegate equivalents" understates Obama's popular vote margin. He won big in large counties like Polk (Des Moines) and university counties like Johnson (Iowa City), which are underrepresented at Democratic state conventions.
John Edwards, in contrast, gamed the delegate system ably by concentrating on rural counties, which are overrepresented. He ended just ahead of or in a virtual tie with Clinton in the official count -- though he ran behind in the popular vote. His vote was down sharply in Polk County, which he carried four years ago. Even though Edwards has been stumping hard in Iowa for six years, he appears to have come in slightly behind his showing in 2004, when he ended up a close second to John Kerry.
Edwards will probably shoulder on in New Hampshire, but it has an aversion to Southerners, and he finished a poor fourth last time around. With far less money than Clinton or Obama, his candidacy appears headed to an unhappy end.
So the Democratic race is now most likely a two-candidate contest between Obama, who can bring large numbers of new and young people into the caucus process, and Clinton, who has the vestigial loyalty of the party's historic constituencies but, at least in Iowa, not a whole lot more.
