Democratic presidential candidate and Vermont U.S. Senator Bernie Sanders leads rival Hillary Clinton by one point among Iowa caucus-goers, in a poll released this morning by Quinnipiac University. It found 41-percent of likely Democratic participants back Sanders, while 40-percent chose former Secretary of State Clinton.
The poll has a margin of error of plus-or-minus 3.4 percentage points.
This is a change from a Quinnipiac poll in July, which showed Clinton at 52-percent, and Sanders at 33.
Two other recent polls have also suggested the race between Clinton and Sanders is a close one, though Clinton maintained her lead in both. A poll in late August by the Des Moines Register and Bloomberg Politics found Clinton the choice of 37-percent of likely caucucs-goers, compared to 30-percent for Sanders.
The latest Quinnipiac poll found likely caucus-goers say Sanders is a more honest and caring candidate. That poll also puts Vice President Joe Biden at 12-percent, though he has yet to formally announce whether he will run for president or not.
