U.S. Sen. Bernie Sanders is leading the Democratic presidential primary field in Wisconsin, according to the latest Marquette University Law School poll, the second survey this week showing the Vermont senator with a double-digit lead in the state.

The new results, released Thursday, list Sanders with 29% support, followed by former New York City Mayor Mike Bloomberg at 17% and former Vice President Joe Biden at 15%.

The findings largely track with a separate survey this month from the UW-Madison Elections Research Center, where Sanders was favored by 30% of respondents, while Biden and Bloomberg were tied for second place with 13% each.

Still have ground to make-up in WI for the general election though. Gonna be tough there.
