The general election for president remains tight, while former Vice President Joe Biden leads Vermont U.S. Sen. Bernie Sanders for the Dem nomination in Wisconsin according to the latest Marquette University Law School Poll.

For the general election, 48 percent backed Joe Biden, who has surged to a lead in the Dem nomination contest since the previous Marquette poll in February. Meanwhile, 45 percent support Trump.

Forty-seven percent favored the president when paired with Bernie Sanders, who was at 45 percent.

Those numbers are unchanged from February, when Biden and Trump were tied at 46.

In the Dem primary, 62 percent back Biden, while 34 percent support Sanders.

Among those who indicated they are absolutely certain to vote or have already voted, it was Biden 65, Sanders 32.

The poll warned with the spike in absentee ballots and an unknown Election Day turnout, the findings “should be viewed with more than the usual caution.”

The February poll was conducted before the Dem primary field began to winnow.

The survey had Sanders leading the bigger field at 29 percent, while Biden was at 15 percent.

The poll of 813 registered Wisconsin voters was conducted using live interviewers over landlines and cellphones March 24-29. The margin of error for the overall sample was plus or minus 4.2 percentage points.

In the Dem primary, the overall question was asked of 394 voters and had a margin of error of plus or minus 5.9 percentage points. Of those, 315 indicated they absolutely would vote or already had, resulting in a margin of error of plus or minus 6.6 percentage points.

With leaners included, the partisan makeup of the poll was 46 percent Republican, 46 percent Dem and 7 percent independent. The long-term trend is 45-45-9.
