Peter Robinson was a speech writer in the Reagan White House. He is also the author of the book How Ronald Reagan Changed My Life.
Thus his opinion on which candidate or candidates are true “Reagan Conservatives” should carry some weight.  He addressed that very question in a blog post today.
{btw… I don’t plan to turn this blog into non-stop promo for my favored candidate like, oh, say, Hugh Hewitt has done with his.)
