Biden holds wide lead over Sanders in Arizona: poll

Former Vice President Joe Biden has a 28-point lead over Sen. Bernie Sanders (I-Vt.) in Arizona, according to a new poll. 

Biden has the support of 45 percent of likely Democratic primary voters in the OH Predictive Insights poll released Monday. 

Sanders is supported by 17 percent. 

Respondents were also asked about Sen. Elizabeth Warren (D-Mass.) and Michael Bloomberg, who have since dropped out of the 2020 race, however. Warren received 13 percent support and Bloomberg followed with 12 percent. 

Biden leads Sanders by 25 points among white voters, based on the survey, which also found that the former vice president also tops the Vermont senator by 29 percent among non-white and non-Hispanic voters and by more than 30 points among Hispanic voters. 

Sanders and Biden will face off in six contests on Tuesday. The former vice president is entering the next round of voting with a lead in delegates, after big wins last week on Super Tuesday. 

Arizona will hold its primary a week from Tuesday. 

The new poll is based on 398 completed surveys with a margin of error of 4.9 percentage points. It was conducted between March 3 and 4.
