Barack Obama has won the Iowa primary. Half of voters chose Mr. Obama, a first-term African-American senator from Illinois beating the frontrunner Hillary Clinton by a significant margin. Of particular note was the makeup of voters: 22% were under age 29, five percentage points higher than in 2004. More than half were first-time caucus-goers.

On the Republican side, was former baptist minister Mike Huckabee who won largely on the strength of late-breaking support from fellow Christian conservatives. Huckabee has come out strongly against gay rights and abortion but does play in a band named Capitol Offense.

2008's election is perhaps the most significant American general in many years, with not just Americans, but the entire world looking at the outcome.
