Hillary Clinton has lost her status as the frontrunner in the race for the Democratic presidential candidate, a new poll revealed.
A survey conducted by NBC News/Marist showed that Clinton has lost her lead to fellow Democratic presidential candidate Sen. Bernie Sanders, who now holds a commanding nine-point lead over the former Secretary of State.
In July, a similar poll showed Clinton leading over Sanders by as much as 10 percentage points. Clinton recently figured in a controversy for using a private email server during her time as Secretary of State, leading to accusations that she might have caused the leakage of top-secret intelligence information.
The same survey also showed that Sanders is already gaining ground on Clinton in Iowa, considered as one of the areas whose primaries more often than not indicate the results of the White House race.
Sanders managed to chip away Clinton's lead among possible Democratic voters in Iowa by only 13 percentage points, according to the survey. Clinton got the nod of 38 percent of the respondents, while Sanders got the approval of 27 percent.
In New Hampshire, another area where primaries are considered crucial, Clinton is only a distant second to Sanders, garnering only 32-percent from the respondents. The Vermont senator got support from 41 percent of the state's likely Democratic voters.
Aside from Sanders, the survey also revealed another possible threat to Clinton's road to the White House: Vice President Joe Biden. The poll showed Biden being more popular than Clinton among both Democrats and the general electorate.
This survey has margin of error of 5.3 percent.
Among Republican presidential hopefuls, meanwhile, controversial businessman Donald Trump is still the top choice with 29 percent of the vote of likely GOP voters in Iowa. He is closely followed by conservative neurosurgeon Ben Carson.
All other Republican presidential aspirants have single-digit figures: Jeb Bush got 6 percent; Carly Fiorina, Rand Paul and Scott Walker got 5 percent; and Ted Cruz, Marco Rubio and Bobby Jindal received 4 percent.
