The Cook County Democratic Party yesterday unanimously re-elected Joseph Berrios to a sixth two-year term as its chairman.

While the event lacks much of a surprise today, this time a year ago, Berrios’ leadership seemed to be in doubt, as the alderman he backed in his 31st Ward was defeated by political newcomer Millie Santiago, despite millions of dollars available to the campaign and a vaunted ward organization at his disposal.

Since then, Berrios seems to have mended fences with fellow Northwest Side pols, affording him a bit more breathing room.

In addition, the party unanimously re-elected its eight other officers – Cook County Board President Toni Preckwinkle, executive vice-chairman; State Rep. Lou Lang, executive vice-chairman; Cook County Commissioner Tim Bradford, first vice-chairman; Ald. Carrie Austin, city vice-chairman; State Sen. Don Harmon, suburban vice-chairman; Norwood Township Comm. Robert Martwick, Sr., secretary; State Sen. Antonio Munoz, treasurer, and County Recorder of Deeds Karen Yarbrough, sergeant-at-arms.
