Former Vice President Joe Biden and Senator Bernie Sanders (I-VT) are locked in a dead heat in the final Iowa caucus polls, released early Sunday, leaving the outcome of Monday’s first-in-the-nation presidential contest up for grabs.
Although the Des Moines Register abruptly pulled their poll Saturday night, after discovering that former South Bend mayor Pete Buttigieg may have been left off some questionnaires because of user error, both Monmouth and CBS News reported results in battleground tracker polls that put Sanders just one point ahead of Biden going into the final stretch.
