Wisconsin voters have a better impression of Donald Trump's running mate Mike Pence than Hillary Clinton's vice presidential pick Tim Kaine.

More than a third of people polled don't have an opinion of either of them.

A Marquette University Law School poll released Wednesday shows 37 percent of registered voters have a positive view of Pence, while 26 percent have a positive opinion of Kaine.

The poll was conducted after the first vice presidential debate. Wisconsin Gov. Scott Walker helped Pence prepare for the debate.

Thirty-four percent of respondents say they don't have an opinion of Pence, while 42 percent didn't have one of Kaine.

The poll of 1,000 registered voters has a margin of error of plus or minus 3.7 points.
