A poll released today by Bloomberg Politics in conjunction with the Des Moines Register shows that the Sanders surge is far from over.

Bernie Sanders now only trails Hillary Clinton by 7 points in Iowa.

According to responses from 404 likely Democratic caucus-goers, 37% would support Clinton, while 30% would support Sanders.

As recently as May, Clinton was polling at 57% in Iowa, a 20 point drop, while Sanders went from 16% to 30%, nearly doubling his support.

The Iowa Caucus, which once looked to be safely Clinton’s is now anyone’s game.

As J. Ann Selzer, president of West Des Moines, Iowa-based Selzer & Co. said regarding the shocking poll results, “the era of inevitability is over.”
