Sen. Hillary Clinton (D-NY) took a surprise victory in a close race against Sen. Barack Obama (D-IL) in the U.S. primary election in New Hampshire last night, tightening the race for the Democratic nomination. On the Republican side, Sen. John McCain (R-AZ) defeated former Massachusetts Gov. Mitt Romney, catapulting McCain into the thick of the race.

As a new Daily Analysis points out, New Hampshire voters focused overwhelmingly on economic concerns and anxieties over the effects of globalization. The article notes that some of these concerns are perhaps more representative of the U.S. mood than those expressed in Iowa’s recent caucus, in which Obama and former Arkansas Gov. Mike Huckabee triumphed. CFR.org Issue Trackers examine the policy stances of U.S. candidates on trade and immigration.

In terms of foreign policy, McCain won support from voters who see Iraq as the most important issue (CNN) of the election. McCain has been a leading Republican backer of the Bush administration’s surge policy in Iraq, but surveys show he also garnered a strong share of independent voters dissatisfied with the White House. On the issue of immigration, runner-up Romney scored well with voters—but it was not enough to tip the contest in his favor. Clinton, for her part, has drawn criticism from Obama for her initial vote supporting the Iraq war. McCain and Clinton each lay out their foreign policy positions in recent articles in Foreign Affairs.
