No woman has so defined the American conservative movement. No organizer has been as feared by her adversaries. No conservative has left such a remarkable legacy.

Phyllis Schlafly died this year at the age of 92, but her legacy lives on. And the legendary soldier of the American right left one final message for conservatives before she went to her reward: It's time to go all out for Donald J. Trump.

"The revolution to take back America starts now!" proudly declares "The Conservative Case for Trump."

In her final work, Schlafly linked the Trump candidacy to the book that first launched her into national politics, "A Choice, Not An Echo," which famously attacked the "kingmakers" of the Republican Eastern establishment.

Schlafly saw the struggle between Trump and his elitist opponents as the last battle in the war she waged from 1952 to 2016, fighting against a Republican leadership she charged was selling out the conservative grassroots.

However, "The Conservative Case for Trump" and the election of 2016 is different, because Schlafly had to confront two other challenges.

First, Schlafly's last book lays out the case for Trump to grassroots conservatives, many of whom initially supported Sen. Ted Cruz, R-Texas, and some of whom continue to question Trump's conservative credentials. Second, Schlafly argued the stakes of the 2016 election are nothing short of existential, with American survival, sovereignty and identity on the ballot.

"I know that some well-meaning conservatives find Trump puzzling or even offensive, but I trust that this book – the culmination, for me, of more than seventy years of active involvement in Republican politics – might help sway them," Schlafly wrote.

She pleads with conservatives to understand how the GOP "has proven ineffectual at stopping Obama" and that the historic American nation will not survive another Democrat in the White House.

"President Obama's effort to fundamentally transform America is on the brink of success – despite our having elected Republican majorities in both houses of Congress," she said.

It's a bracing message for frustrated conservative voters who have delivered the Republican Party years, if not decades, of political victories. And yet day by day, year by year, election cycle by election cycle, conservative, patriotic Americans see their culture disintegrating, their traditions mocked, their history deconstructed and the power of the federal government increasing exponentially. The only solution, wrote Schlafly, is nothing short of a political revolution.

"Donald Trump is obviously not Ronald Reagan – no one else is – but I do sincerely believe that Donald Trump can remake our politics as Reagan did, give the Republican Party what has eluded them in five of the last six presidential elections – an electoral college and popular vote majority – and provide dramatic conservative reform," Schlafly said.

As polls continue to tighten, Schlafly's postmortem prophecy seems more likely than ever before. Trump is within 2 points in the state of Pennsylvania, a tempting target for Republicans, and within 1 point in the critical swing state of Colorado. Trump also leads in North Carolina and Florida.

But as Schlafly's book reminds conservatives, Republicans shouldn't need to worry about winning every single battleground state. The veteran political organizer, in a bittersweet passage, reminiscences how the bluest of blue states, California, was once the launching pad for the Reagan Revolution. And Schlafly's dire warning needs to be internalized by every conservative who wants the Republican Party to remain viable in a changing America which, absent massive policy shifts, will soon resemble the Third World.

"The prime motivation behind the left's support for open borders is not to welcome the oppressed … it is a systematic effort to reshape the demographics of the American electorate for the benefit of the Democratic Party," Schlafly charged. "The model is California, which, largely through immigration, has been transformed from the 'Reagan Country' I well remember to the majority minority far left state it is today."

Her last message warns conservatives that what happened to California presages what will happen to the rest of the country unless there is a President Donald J. Trump in January 2017. In "The Conservative Case for Trump," Schlafly presents Trump's immigration policies in detail and urges swift implementation.

"If we're going to turn this thing around, we have to do it fast," she approvingly quotes Trump.

While many grassroots conservatives have embraced the Schlafly/Trump position on immigration, the veteran organizer's last book challenges conservative movement orthodoxy on so-called free trade. "The Conservative Case for Trump" defies corporate America's support for international trade agreements such as the Trans-Pacific Partnership and calls for the conservative movement to oppose any surrender of American sovereignty. Instead of championing big business, Schlafly told conservatives to stand with American workers.

"Before Donald Trump, there had been no effective national political spokesman for the American worker," she said. "Now there is."

In her last book, Schlafly also forthrightly addressed one of the topics that makes conservative uncomfortable – Trump's tendency to put his foot in his mouth with his blunt pronouncements. But rather than seeing it as a weakness, Schlafly called it a strength. And she told conservatives to stop playing by the left's rules and succumbing to the deadly taboo of political correctness.

"All politicians say stupid or offensive things, but Democrats – with the help of the Democrat-friendly media – brush their stupid comments aside and move on, while Republicans actually amplify their mistakes, criticizing their own in extreme terms, pandering to the political correctness of the left," Schlafly wrote. "Like no president since Ronald Reagan, Trump will come into office with his own plan, his own agenda – one that pays no mind to the agenda of the political establishment or the enforcers of political correctness. He is quite happy to say what he thinks whether it is politically correct or not – and he will speak politically incorrect truths that no one else will say."

Schlafly's message is a powerful testimony to the conservative voters she fought for her entire life. And as Hillary Clinton is counting on so-called #NeverTrump conservatives to stay home so she can once again enter the White House, "The Conservative Case for Trump" is arguably the most important book during this most important of elections. The climax of one of the most influential lives in American history, "The Conservative Case for Trump" is a must for every conservative activist, every patriot concerned about America and everyone who wants to understand American politics at this extraordinary time.
