A recent CNN/ORC poll shows that more than half of all Americans who participated in the survey viewed Democratic presidential hopeful Hillary Clinton as unfavorable.

ORC International interviewed 1,001 Americans for the poll, including 897 interviews with registered voters. Of the sum, 55 percent of voters viewed the former secretary of state as unfavorable.

Vice President Joe Biden was viewed as the most favorable in both groups for the Democratic Party, should he choose to join the presidential race. Clinton made it second in the polling as the most favorable amongst all Americans and registered voters.

Twenty-five percent of registered voters say they never heard of Sen. Bernie Sanders, I-Vt. Yet, 36 percent viewed him as a favorable candidate. Twenty-nine percent of registered voters viewed him as unfavorable.

Meanwhile, a new poll finds Clinton just six points ahead of Donald Trump, making the billionaire businessman competitive in the general election, according to CNN.

Although Clinton still holds the overall likelyhood of winning the presidential bid, Trump and two other Republican contenders are matched against the former first lady.

Clinton's 53 percent unfavorable rating marks the most negative rating for the former secretary of state since March 2001. Yet, 52 percent of women view her favorably, crediting her strong support for women's rights.

An ongoing investigation of Clinton using private emails during her time as secretary of state has made headlines, painting her in a bad light. But 37 percent of independents say she did nothing wrong by using the personal email system.

At the same time, Jeb Bush holds an advantage among men by 51 percent, leading Clinton in that demographic.

Biden could be Clinton's biggest competitor for the Democratic nomination since most Democrats say they would like to see the VP run for president.

Clinton has an overall 47 percent support from Democratic voters.
