MUSCATINE, Iowa (AP) — A growing trend has emerged in the states that matter most in the Democratic Party’s high-stakes presidential nomination fight: Primary voters appear to be getting less certain of their choice as Election Day approaches. The growing uncertainty is in part a reflection of the historically large number of candidates still in the race. But it also reflects a deepening sense of unease about the party’s top-tier candidates whose political liabilities are becoming more visible as the first voting contests approach.

Interviews with dozens of voters across Iowa and New Hampshire in recent days reveal a pervasive feeling of uncertainty. And even among those who have a favorite candidate, most say they could change their mind before voting begins.
