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 percent of respondents, while Sanders captures the support of 31 percent. Vice President Joe Biden, who has not yet announced a decision about whether he will jump into the presidential race, clocks in at 12 percent.
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 one percent.
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 percent to 37 percent.
According to the new Iowa poll, more Democrats give Sanders high marks for being honest and trustworthy (35 percent) than Clinton (28 percent).
There is also a significant gender gap. Among women, Clinton leads Sanders 58 percent to 26 percent, 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.
