One need not look further than Donald Trumps ascendancy to the top of the GOP candidate heap to know that Americans have become disillusioned with the political establishment. James Piereson takes a look at previous political revolutions that have already taken place in this country. Piereson tells us that another is on its way. His latest book, Shattered Consensus, is a masterwork of historical and political analysis and should not be missed. On a positive note, Piereson is not another crying out from the wilderness that America will fall. On the contrary, he believes that any current political turmoil is a precursor to another period of growth for the nation.
