Bernie Sanders appears to have widened his lead over Hillary Clinton in Iowa less than two weeks before the Democratic caucus is held there.
Sanders, an independent senator from Vermont, currentlyÂ holds the support of 51 percent of likely Democratic caucus-goers in the state, according to aÂ CNN/ORC poll released Thursday. Clinton, in comparison, maintains 43 percent of the vote.
This indicates a substantial increase in Sandersâ supportÂ since the same question was askedÂ late last year. Clinton led Sanders 54 to 36 percent when likely Iowa caucus-goers were surveyed between November 28 and December 6, 2015.
The most current survey, conducted between January 15 and 20, also found that a majority ofÂ Democratic voters in Iowa sayÂ that they have made up their mindsÂ on whoÂ to vote for come February.
Earlier this month, a Quinnipiac University poll showed that Sanders had a slight five-percentage-point lead over Clinton in Iowa. Widely considered to be the likely nominee, Clinton is also trailing Sanders in New Hampshire, another key early voting state.
Clintonâs campaign has been intensifyingÂ its attacks on Sanders in recent weeks, as his poll numbers have risen. Sanders has pointed to the attacks as evidence that the campaign is âin serious trouble.â
The new year has also brought fresh developments in the controversy surrounding the former secretary of stateâs use of private email. Earlier this week, reports surfaced that an intelligence review had concluded that some of Clintonâs emails contained intelligence from the governmentâs highlyÂ classifiedÂ âspecial access programs,â which is more sensitive than âtop secretâ information.
