Warren's rise shakes up Democratic field

Warren's rise shakes up Democratic field-thehill: A new poll showing Sen. Elizabeth Warren (D-MA) leading former Vice President Joe Biden in Iowa has shaken up the Democratic nomination battle, and insiders across the party are gaming out what it all means. Warren currently has 22 percent support to Biden’s 20 percent, according to the well-respected Des Moines Register–CNN–Mediacom poll, released Saturday night. The two are well clear of the rest of the field, with Sen. Bernie Sanders (I-VT) in third place with 11 percent support.
