Warren currently tops the list of voters' preferred second choices at 26 percent, with Sanders coming behind her at 18 percent.

The survey also shows that roughly 3 in 4 supporters of Sanders and Warren identify themselves as liberals, contrasted by just 4 in 10 Biden supporters. 

The survey of 628 registered Pennsylvania voters, including 292 Democrats, 251 Republicans and 85 independents, was conducted from Jan. 20 to 26 with a margin of error of 6.2 percentage points.
