Gretchen Whitmer illustrated how to win

Gretchen Whitmer shows Democrats how to win.

She ran on economics and abortion, increased Democratic turnout and persuaded swing voters, all while connecting with the party’s largest base: Black voters. She embodied the way smart campaigns in Pennsylvania, Wisconsin and around the country operated this cycle, and she gave a blueprint for Democrats in 2024.

The first lesson of Ms. Whitmer’s campaign is that economic good news and development — especially building things — really make a difference. Democrats should run on American manufacturing: Whether it was a new semiconductor plant (to help ease the chip shortage facing the auto industry) or generational-level investments from G.M. in electric-vehicle battery plants (to make sure the critical supply chains for electric cars will be based in Michigan, not China, where many E.V. batteries are currently built), Ms. Whitmer fought to bring them to Michigan.

In in multiple TV ads, she told voters, “I can’t solve the inflation problem, but we’re doing things — right now — to help.” She listed tangible benefits that she proposed or got done, like more affordable community college, insurance refunds and tax cuts for seniors. She passed four balanced, bipartisan budgets with no tax increases, and she let voters know about that.

This was paired with a pocketbook attack. Her opponent, Tudor Dixon, took millions of dollars from the wildly unpopular (in Michigan) billionaire Betsy DeVos and her family. For months her campaign highlighted Ms. Dixon’s connections to Ms. DeVos and how Ms. Dixon’s tax plan would benefit Ms. DeVos and hurt the middle class — working-class tax hikes, cuts to schools and the like. Ms. Whitmer also highlighted abortion rights as a vote-deciding issue for swing voters.

Ms. Whitmer also developed a deep connection with Black voters well before she picked as her running mate and governing partner the state’s first Black lieutenant governor, Garlin Gilchrist. After winning Black voters decisively with high turnout in 2018, she deepened that connection

What Ms. Whitmer has done in Michigan can be done by Democrats across the country. We can talk about economics and abortion, we can invest in turnout and persuasion, and we can strengthen our appeal to voters of color while winning over white voters.
