President Donald Trump on Saturday night revved up his campaign pitch to voters in key Rust Belt states by touting the U.S. economy, saying he’s working to stop jobs from moving to neighboring countries, and mocking his Democratic opponents.

“We’re now the No. 1 economy anywhere in the world and it’s not even close,” Trump said at a rally in Green Bay, Wisconsin. He later told the cheering audience that returning for another term in office will make the U.S. stronger: “At the end of six years, you’re going to be left with the strongest country you’ve ever had.”

The president said his renegotiation of trade agreements will make the economy stronger. Trump said Japanese Prime Minister Shinzo Abe, who visited the White House on Friday to discuss trade, agreed to put “US$40 billion into the United States for new car factories.”

The event was the president’s first since his biggest Democratic rival, former Vice President Joe Biden, entered the 2020 race, saying in a campaign video that he’s running because Trump poses a threat to the nation “unlike any I had ever seen in my lifetime.”

Trump scheduled the rally as counter-programming to the annual White House correspondents’ charity dinner in Washington. He has publicly fumed in recent weeks that reporters focused too much on unflattering episodes from special counsel Robert Mueller’s report instead of the conclusion his campaign had not criminally colluded with Russian efforts to disrupt the 2016 campaign.

Russia Investigation

The president renewed those complaints before a receptive crowd on Saturday, repeating his assertion that investigations into ties between his campaign and Russia amounted to a “witch hunt.”

“The radical liberal Democrats put all their hopes behind their collusion delusion, which has now been totally exposed to the world as a complete and total fraud,” he said.

Mueller’s report didn’t find an “underlying crime” by Trump related to Russian interference in the 2016 election. But the report provided an exhaustive account of Trump’s efforts to head off or undermine the probe, saying Congress could take action on at least 10 instances of potential obstruction of justice. Attorney General William Barr said he determined obstruction didn’t take place.

Wisconsin will be a crucial battleground for Trump, no matter who Democrats select as their nominee. It’s among a trio of Great Lake states –- along with Michigan and Pennsylvania –- that were thought to be reliably Democratic before Trump’s 2016 victory.

Despite dominant fundraising, an established campaign organization and the power of incumbency, Trump risks losing all three states in 2020 after Republican failures in midterm elections showed his support in the region is fading. Any Democratic challenger will likely need to win all three to prevent Trump from securing a second term in the White House.

Rust Belt Jobs

At the rally, Trump highlighted jobs being created in Wisconsin, Pennsylvania, Michigan and elsewhere, crediting the trend with his moves to rescind regulations and counter tariffs on American exports.

Trump said he’d saved “countless timber jobs,” including in Wisconsin, by imposing new tariffs.

He also invoked Commerce Department data reported Friday showing faster-than-expected growth in the U.S. economy, and said manufacturing jobs are returning. Gross domestic product rose at a 3.2 per cent annual rate in the first quarter of 2019.

Trump said trade deals he’s negotiating would bring new jobs to Wisconsin and other Rust Belt states. He urged supporters to call on their members of Congress to ratify a trade deal his administration negotiated with Mexico and Canada, saying it would help prevent jobs from leaving the U.S. and going to those countries.

On immigration, Trump said he’s sending migrants caught crossing the southern border into the U.S. to so-called sanctuary cities -- most of them Democratic strongholds -- if they can no longer be legally detained. "I’m proud to tell you that was actually my sick idea," he said.

Wisconsin has earned particular notoriety after Trump’s 2016 opponent, former Secretary of State Hillary Clinton, didn’t campaign in the state during the general election. The Democratic National Committee scheduled its 2020 convention in Milwaukee.

Economic Record

For Trump, the state offers a potentially tricky referendum on his economic record. His administration helped Wisconsin broker a deal with Foxconn Technology Group in which the Taiwanese manufacturing giant said it would create thousands of new jobs building LCD displays in exchange for more than US$4 billion in tax breaks. The company has subsequently said it was reconsidering its plans.

Wisconsin Governor Tony Evers, a Democrat, has said the state is renegotiating the deal as Foxconn has shifted its production plans.

Wisconsin-based Harley-Davidson Inc. has also shifted some production overseas to avoid retaliatory tariffs imposed by European countries after the U.S. hiked taxes on imported steel and aluminum. The company said in January that the tariffs will cost the company between US$100 million and US$120 million in 2019, and reported slumping first-quarter profit on Tuesday.

Trump has called the European tariffs on the motorcycle manufacturer “so unfair” and vowed retaliation in a tweet earlier this week. White House officials have not said how or when the president would move on that threat.

On Saturday night, Trump repeated names he’s given to Democratic challengers. He called Biden “Sleepy Joe,” dubbed Senator Bernie Sanders “Crazy Bernie” and Senator Elizabeth Warren of Massachusetts “Pocahontas” in reference to her claims of Native American ancestry. He said he has no Native American blood -- and that’s more than she has.

“She’s finished, she’s out,” Trump said of Warren.
