Nah.... Plenty of other folks have seen and written about the slow creep of socialism, and to much greater practical effect. (See the early history of National Review, for example, which helped to lay the foundations for Reagan's revolution.)
Rand's "strength" is in drawing caricatures of people to illustrate her ideas. That tendency is actually far more harmful to our side than anything the left does. When one looks at the world as so thoroughly black and white Rand painted it, one is left unable to deal with the world (and the people in it) as they actually exist.
One look at the lamentably awful state of American politics these days is enough to demonstrate the dangers inherent in dealing with caricatures.
