From Phyllis Schlafly, the woman whose celebrated classic A Choice, Not an Echo upended the 1964 Republican Convention, comes a persuasive new argument for a surprising conservative choice: Donald Trump.

For the first time since 1980, a significant number of Republicans are considering abandoning their party’s nominee. This is a grave mistake, Schlafly says, because a Donald Trump “radical redirection” could actually set America back on the path of Reagan’s conservative revolution.

In The Conservative Case for Trump, Schlafly and coauthors Ed Martin and Brett M. Decker set aside the circus of the campaign and zero in on eight defining points of the Trump agenda to convince Republican voters that Donald Trump—improbable as it may seem—is the true conservative they’ve been waiting for.
