DES MOINES, Iowa - A new CBS News poll shows both former Vice President Joe Biden and Senator Bernie Sanders tied for first place in the Iowa caucuses...at 25 percent each.
Pete Buttigieg is third with 21 percent, followed by Senator Elizabeth Warren at 15 percent and Senator Amy Klobuchar at 5 percent.
The poll's margin of error is 3 percentage points.
Also over the weekend, the Des Moines Register decided not to release its highly anticipated final Iowa Poll after complaints of a polling error.
The cancellation came after Pete Buttigieg’s campaign raised concerns that he was not included in at least one phone call. The campaign said that an Iowa supporter received a poll phone call from a polling operation which did not include Buttigieg's name in the menu of options.
