To say the poll was highly anticipated is an understatement. The poll is the first significant survey from Iowa in nearly two months, a drought that has left a murky picture of the Democratic primary race in a state that conducts its first-in-the-nation caucuses. Iowans famously break late, sometimes making their final decision in the weeks and days before the caucuses occur, and every campaign will be scrutinizing the results for signs that their candidate is strengthening — and that their rivals are weakening — heading into the final stretch.
