Former Vice President Joe Biden is the runaway favorite to win the 2020 Democratic nomination according to a new poll that also charted the emergence of two new potential challengers -- Starbucks boss Howard Schultz and Disney CEO Bob Iger.

Biden crushes the opposition in the Morning Consult survey with a 74 percent favorability rating. It was the second poll in a week to show Biden in the 2020 Democratic driver's seat.

Second at 51 percent favorable is Massachusetts Sen. Elizabeth Warren followed by surging Minnesota Sen. Al Franken at 45 percent.

Schultz and Iger showed that they would have a base of support to build on if they decided to jump in. Schultz had a 21 percent favorability rating, Iger is at 19 percent.

For Biden, the survey is very encouraging as he eyes a bid to challenge President Trump. He ran three times before, never doing well, but was rewarded the vice presidency by former President Obama.

The survey wasn't a great showing for another hopeful, Virginia Gov. Terry McAuliffe, at 22 percent and far behind the 2016 vice presidential nominee and fellow Virginian Sen. Tim Kaine, at 37 percent.
