Obama is the last Democrat who won Wisconsin with more than 50 percent of the vote. Hillary Clinton lost Wisconsin by 22,748 votes in 2016, and Joe Biden won by 20,862 in 2020. No candidate of either party secured a majority in either of those Wisconsin elections. Contrast that with Obama, who in 2008 won 56 percent of the vote in Wisconsin, far above the 53 percent he won nationally. In 2012, a tougher year for Democrats, Obama won 53 percent of the Wisconsin vote, way more than the 51 percent he won nationally.

Obama’s Wisconsin wins were the biggest for Democrats in the state since Lyndon Johnson’s in 1964 and Franklin Roosevelt’s in 1936. And the Obama victories were truly statewide in character: He won dozens of rural counties, along with the urban centers where Democrats have traditionally been strong. In 2008, he carried seven of the state’s eight congressional districts—including several that FDR lost in his later bids. In 2012, Obama carried fewer congressional districts, but still won vast stretches of the state, including every county in southwest Wisconsin and much of the northwest.

It is unlikely that any Democrat could run as well in Wisconsin as Obama did in 2008. But Harris can, and should, aspire to win as much of the Wisconsin vote as Obama got in 2012—when the party also won US Senate races and carried a solid majority of the vote statewide for congressional and legislative seats. Gerrymandering prevented the Democrats from getting their fair share of seats that year. But newly drawn, fair maps could give the party much more traction this year.

With the right campaign, Harris, who is narrowly ahead in recent polls of Wisconsinites, could lead the Democrats to a similarly significant victory.

But she won’t do so by going on and on about Dick and Liz Cheney.

It’s Obama who has the potential to persuade Wisconsin voters, via targeted media ads and, ideally, a high-profile appearance in the state with this year’s nominee.

Obama gets Wisconsin. He has always maintained a strategic sense about how to campaign in the state, where he won the 2008 Democratic presidential primary over Hillary Clinton by a commanding 58 to 40 margin.

Obama, who as a young man worked with a Chicago-based law firm that maintained an office in Madison, knows where to campaign in the Badger state. In 2008 and 2012, he did the usual outreach to urban voters in Milwaukee and Madison. But he also paid attention to smaller cities, such as Green Bay, Racine, Kenosha, Janesville, Wausau, La Crosse, and Eau Claire, where he showed up and spoke, a lot, about renewing manufacturing and increasing support for rural regions of the state. He also talked about the cost of bloated military budgets and unnecessary wars. In 2008, Obama positioned himself to the left of Clinton in the primary race—emphasizing the fact that he had opposed the rush to war in Iraq.

That position appealed to voters in Wisconsin, which was a historic center of opposition not just to the Vietnam War in the 1960s and ’70s but also to World War I. It was Wisconsin Senator Robert M. La Follette who counseled voters, “Stand firm against the war and the future will honor you. Collective homicide cannot establish human rights.” The pundits said those sentiments would ruin La Follette politically. Instead, he was reelected by the largest landslide in the history of Wisconsin Senate contests. It was similar for Senator Gaylord Nelson, who bucked a Republican tide to secure reelection in 1968 as an ardent foe of the Vietnam War. And for Senator Russ Feingold, who voted against the war in Iraq in 2002—as he had opposed the Patriot Act in 2001—and then won his biggest victory ever in 2004.

Obama recognized that tradition and embraced it in 2008, making a break with leaders of both parties to decry “a Washington where politicians like John McCain and Hillary Clinton voted for a war in Iraq that should’ve never been authorized and never been waged—a war that is costing us thousands of precious lives and billions of dollars a week that could’ve been used to rebuild crumbling schools and bridges; roads and buildings; that could’ve been invested in job training and child care; in making health care affordable or putting college within reach.”

It may be harder for Harris to break with an administration in which she serves. But it would be wise for her to recognize that a stronger stance in favor of a ceasefire in Gaza—and for restrictions on US military aid to Israel—would attract far more support in Wisconsin than an appearance with a neoconservative militarist like Liz Cheney.

Indeed, if Harris appears with anyone in Wisconsin, it should be Obama. He knows how to speak to the sentiments of the state, how to campaign effectively in its communities, and how to win it big on Election Day.
