(CNSNews.com) -- A new poll of Wisconsin voters shows that in the race for president, Donald Trump currently leads against the four top Democrats vying for their party's nomination: Joe Biden, Bernie Sanders, Elizabeth Warren and Pete Buttigieg.
In addition, 53% of registered voters in Wisconsin say Trump should not be impeached while 40% say he should.
The poll by Marquette University Law School was conducted Nov. 13-17 with a sample of 801 registered voters in Wisconsin interviewed by telephone. The margin of error was +/- 4.1 percentage points.
If the presidential election were held today, the poll shows Donald Trump leading Joe Biden 47% to 44%. Trump leads Bernie Sanders 48% to 45%. Trump leads Elizabeth Warren 48% to 43%, and Trump outpaces Pete Buttigieg 47% to 39%.
In the 2016 election, Hillary Clinton was favored to win Wisconsin. Trump beat her 47.22% to 46.45%. Trump earned 1,405,284 votes and Clinton fell short at 1,382,536 votes -- a very close race.
In an October poll of Wisconsin voters, Trump was losing to Biden (50-44), Sanders (48-46), and Warren (47-46). Despite the impeachment inquiry, voters in Wisconsin apparently are leaning more towards Trump, although the numbers are still close.
In the vote-by-party-affiliation category, the November poll showed Independents favor Trump over Biden 39% to 33%, favoring Trump over Sanders 42% to 35%, favoring Trump over Warren 43% to 34%, and choosing Trump over Buttigieg 35% to 25%.
On bread and butter issues, "fifty-five percent of those polled approve of Trump’s handling of the economy, while 43 percent disapprove," according to the poll. "In October, 51 percent approved and 45 percent disapproved."
Also, 54% of Wisconsin voters approved of Trump's handling of foreign policy, while 52% said they disapproved.
In summary, the pollsters said, "While the shifts in opinion on both impeachment and presidential preferences are not large, they are consistent across multiple questions in the poll. That includes increases in support for Trump’s work on foreign policy and the economy."
