Seriously, it is coming on Friday:

“WASHINGTON — With Donald J. Trump and Senator Ted Cruz battling for the Republican nomination, two powerful factions of their party are now clashing over the question: Which man is more dangerous?

Conservative intellectuals have become convinced that Mr. Trump, with his message of nationalist-infused populism, poses a dire threat to conservatism, and plan to issue a manifesto on Friday to try to stop him.” …

Rich Lowry, editor of National Review — embracing the role of his predecessor, William F. Buckley, who in the 1950s confronted Birch Society members — has reached out to conservative thinkers to lend their names to the manifesto against Mr. Trump. He has drawn some of the country’s leading conservatives, including Erick Erickson, William Kristol and Yuval Levin, to write essays buttressing the argument that Mr. Trump has no commitment to restraining the role of government and possesses authoritarian impulses antithetical to conservative principles.

“Donald Trump is a menace to American conservatism who would take the work of generations and trample it underfoot on behalf of a populism as heedless and crude as The Donald himself,” the magazine says in an editorial that will anchor a coming special issue.”
