Kamala Harris, 2024: Obamacare will do.

Kamala Harris has sharply shifted her positions on several key issues since 2019, when she ran a brief and unsuccessful presidential campaign. The worst political interpretation is that she’s a shape-shifting opportunist who changes her message based on the audience she’s addressing.

But maybe that’s a good thing. The British economist John Maynard Keynes famously said, “When the facts change, I change my mind.” As the Democratic presidential nominee in 2024, Harris’s situation is notably different than it was in 2019, when she was trying to break out of a pack of mostly progressive Democrats wooing the left. She doesn’t have to do that in 2024. What she has to do now is win centrist voters in swing states to defeat Republican nominee Donald Trump and clinch the White House.

Voters can legitimately ask if Harris is now pitching moderate policies she doesn’t actually support and will move back toward the left if she gets elected. She could. But the progressive policies Harris backed in 2019 weren’t realistic in the first place. She has migrated to ground that’s much easier to defend because it aligns much more closely with public opinion.

Harris jumped on the Green New Deal bandwagon in 2019 as part of an effort to drive action to address climate change during the Trump administration, which was moving in the opposite direction. The Green New Deal never had a chance of passing Congress as legislation or getting enacted in its original form. It would have dramatically disrupted the energy and transportation sectors and banned the revolutionary “fracking” drilling technique that has generated a surge in US oil and natural gas production. Energy costs would have soared, enraging voters. At best, the Green New Deal was a symbolic statement of resolve to do something about global warming.

President Biden and his fellow Democrats have, in fact, done something about global warming. The misnamed Inflation Reduction Act that Biden signed into law in 2022 is the biggest set of green energy incentives ever enacted in the United States. That legislation is also much smarter than the Green New Deal. It incentivizes green energy adoption but doesn’t penalize fossil fuel use or ban any type of energy.

Harris, in fact, is now staking out a more centrist stance on energy than Biden himself, who was never a supporter of the Green New Deal. In the Sept. 10 debate with Donald Trump, Harris pointed out that oil and natural gas production has hit record highs during the last two years, something Biden never mentions. That should be a bragging right for any president who wants credit from voters for plentiful, affordable energy. Harris is lunging for that credit.
