Democratic presidential candidate Hillary Clinton widened her lead over rival Sen. Bernie Sanders (I-VT) among Democrats in Iowa, according to a Bloomberg Politics/Des Moines Register poll released Monday.
Clinton had 48 percent support from likely Democratic caucusgoers in the survey, while Sanders had 39 percent support and former Maryland Gov. Martin O’Malley had 4 percent support.
In the same poll in October, Clinton led Sanders 42 percent to 37 percent.
The poll was conducted by Selzer & Co. of Des Moines from Dec. 7-10 by phone among 404 likely Democratic caucusgoers. The margin of error was plus or minus 4.9 percentage points.
