Phyllis Schlafly, the conservative polemicist and activist icon who passed away September 5, is beating Democratic presidential nominee Hillary Clinton in the book market despite intense public interest in the 2016 campaign.

Schlafly’s The Conservative Case for Trump (Regnery), which was released on Labor Day, Sep. 6 — coincidentally, the day after she died — outsold Clinton’s Stronger Together: A Blueprint for America’s Future, which was released on the exact same date.

Early sales figures provided by Regnery showed that Schlafly had moved 4,296 units, compared to 2,905 for Clinton.

The fact that Schlafly beat Clinton by nearly 50% is no surprise to Ed Martin, her co-author on The Conservative Case for Trump.

“I think Phyllis is looking down in heaven and enjoying this,” he told Breitbart News on Sunday. “Phyllis, among other talents, had increibdle timing.

“She used to tell me that you have to know when and how to pick your battles. I can’t say we expected her to pass away when we wrote the book. I was hoping to have something by July. She told me, ‘Don’t worry, it will be fine if it gets out by Labor Day.’

He said that many Americans continue to find Schlafly a source of inspiration, even after her passing at the age of 92.

Schlafly endorsed Trump in the Republican primary, causing controversy among conservatives who had rallied behind Sen. Ted Cruz (R-TX) as the clear ideological favorite.

But Schlafly placed special emphasis on the issues of trade and immigration, Martin said — issues that Trump set at the forefront of his campaign.

“The fist two chapters of the book are about immigration and trade. She talked to Donald Trump about conservative judges, but she believe that immigration and trade are transformative issues. Unless we take those issues seriously, conservatives need to realize we won’t win another election, we won’t have a country. She felt that is what is at stake.”

Schlafly also felt that conservatives had to “get over misgivings” and pick the Republican nominee.

“I would say what I heard Phyllis Schlafly say: ‘If you want a third, fourth, or fifth party, go to Europe. The conservative party in America is the Republican Party, and we cannot keep going the direction we have been under Obama and Clinton.”
