CEDAR FALLS, Iowa (AP) - When Bernie Sanders rolled into Decorah, nearly 2,300 people were waiting for him. Chants of "Feel the Bern" filled the spirited hall from a crowd roughly equivalent to a quarter of the town's population. "If we have the kind of turnout that I hope we can," Sanders told the rally, "then we're going to win here in Iowa."

Two days later, on Tuesday, Hillary Clinton received a far less raucous greeting in the same northeastern Iowa college town. A largely elderly crowd of 450 listened quietly, clapping politely at her applause lines.

It's all beginning to resemble a bad flashback for the second-time Democratic presidential candidate, who once again finds herself barnstorming through the frozen stretches of Iowa with a diminished lead in the polls and an underdog rival on the rise.
