Hillary Clinton holds a solid lead over Democratic rival Bernie Sanders in the key early nominating state of Iowa, a new poll shows.
The CNN/ORC poll of likely Democratic caucus-goers shows that Clinton is the top choice of 50% of respondents, while Sanders captures the support of 31%. Vice President Joe Biden, who has not yet announced a decision about whether he will jump into the presidential race, clocks in at 12%.
All other Democratic rivals – former Maryland Gov. Martin O’Malley, former Virginia Sen. Jim Webb and former Rhode Island Gov. Lincoln Chafee – poll at less than 1%.
The new numbers come after a Franklin Pierce University/Boston Herald poll showed Sanders leading Clinton in New Hampshire, another key early nominating state, 44% to 37%.
According to the new Iowa poll, more Democrats give Sanders high marks for being honest and trustworthy (35 percent) than Clinton (28%).
There is also a significant gender gap. Among women, Clinton leads Sanders 58% to 26%, while the two candidates run about even with men.
The poll of 429 Democratic caucus-goers was conducted August 7-11 and has a margin of error of +/- 4.5 percentage points.
