President Donald Trump leads in head-to-head matchups against all 2020 Democratic hopefuls by significant margins in the crucial swing state of Wisconsin, a new poll released on Thursday, Feb. 20, indicated. 

President Trump leads the Democratic front-runner Sen. Bernie Sanders (I-Vt.) by 43% to 50%, former Vice President Joe Biden 42% to 49%, former New York City Mayor Michael Bloomberg 41% to 49%, and former South Bend, Indiana, Mayor Pete Buttigieg 41% to 49%, according to the new Quinnipiac University Poll.

The poll also shows the president’s margin over Sen. Amy Klobuchar (D-Minn.) by a margin of 29% to 50% and Sen. Elizabeth Warren of Massachusetts 41% to 51%.

The president also enjoys his highest job approval rating among voters in Wisconsin (51%-46%). The poll, which was conducted from Feb. 12-18, surveyed 823 registered voters in the state and has a margin of error of roughly 3.4%.

However, the picture is reversed for President Trump in Pennsylvania and he narrowly trailed leading Democrats in Michigan, according to the same poll.

“Three different states, three different scenarios, one constant—the economy,” Quinnipiac University polling analyst Mary Snow said in a statement. “It’s a top issue for voters, and it’s giving President Trump a strong tailwind.”

“Wisconsin voters give him a job approval rating above 50 percent, higher than what he receives nationally and in Pennsylvania and Michigan. These Wisconsin numbers are a red warning sign for Democrats that rebuilding the ‘blue wall’ in 2020 may not be so easy. But it’s a long way to November,” she added.

President Trump scores high marks in all three states for his handling of the economy and the majority of voters said their personal financial situations are better now than they were in 2016.

Economy is the most important issue to voters in all three states, followed by health care and climate change. Wisconsin residents were the most optimistic about their state’s economy, with 76% ranking it excellent or good, Pennsylvania voters came after with 70% and Michigan voters with 63%.

Three critical Rust Belt states delivered a critical victory to President Trump in 2016 over Hillary Clinton.
