Democratic caucus: 'Terrific field of candidates' brings out record crowds

John Edwards balloons, boxes of Hillary Clinton campaign buttons, dozens of Barack Obama signs and hundreds of people in sign-in lines made up the scene of what Iowa Democratic Party volunteers believe was the strongest caucus turnout ever in Iowa.

Volunteers toting T-shirts and boxes of brochures greeted crowds of caucus participants in Charles City, many of whom arrived and started to line up long before the sign-in process began.
