Collin Anderson of the Washington Free Beacon probes Vice President Kamala Harris’ recent unexplained policy shifts.

As a struggling presidential candidate in 2019, Kamala Harris embraced a slew of far-left policy positions on energy, immigration, health care, and guns. Now, as the Democratic Party’s presidential nominee, Harris is tossing those positions aside through anonymous statements to the press.

So what prompted the reversals, and what policies do Harris support now? She hasn’t said.

Harris has yet to lay out a detailed policy agenda or sit for an interview since she was crowned the Democratic presidential nominee, and her campaign website does not include a policy page. But her aides have made clear that her agenda will not be the same as her old one.

During brief exchanges with reporters on Thursday and Saturday, Harris pledged to release a policy platform this week and schedule a formal interview “before the end of the month.” …

… Harris endorsed a total ban on fracking during her 2019 campaign, criticizing the practice as unsafe.

“There’s no question I’m in favor of banning fracking,” Harris said during a Sept. 2019 CNN town hall. “We have to just acknowledge that the residual impact of fracking is enormous in terms of the impact on the health and safety of communities.”

Harris walked back that position one year later, though she did not say she supported fracking herself. Instead, she told CNN’s Dana Bash that she was “comfortable” with Biden’s pledge not to ban fracking. …

… Harris was one of 11 candidates in the 2020 Democratic presidential primary to pledge to decriminalize border crossings.

During a June 2019 debate, then-Telemundo anchor José Díaz-Balart asked participants to “raise your hand if you think it should be a civil offense rather than a crime to cross the border without documentation.” Harris raised her hand.

One year earlier, as a senator, Harris flirted with abolishing the Immigration and Customs Enforcement agency. …

… On Friday, an anonymous campaign official told Axios that Harris believes “unauthorized border crossings are illegal.”
