Is Hillary Boring Democrats in Iowa?

A new poll from NBC News and the Wall Street Journal Sunday gave a shocking assessment of the state of the Democratic caucuses in Iowa. Widely considered the frontrunner and a near-lock for the Democratic nomination, former secretary of state Hillary Clinton appears to be leading her main competition, Vermont senator Bernie Sanders, by just three points in the Hawkeye State.

Clinton’s 48 percent to Sanders’s 45 percent in the NBC poll reflects a big boost for Sanders over the past several months of NBC’s polling, while Clinton’s support has stagnated over the same time. The Real Clear Politics average of Iowa polls still gives Clinton a 10-point advantage, but another recent poll from CBS News and YouGov gave her just a 5-point lead there.
