From George Romney’s letter of December 21, 1964, to Barry Goldwater:
“We need only look at the experience of some ideologically oriented parties in Europe to realize that chaos can result. Dogmatic ideological parties tend to splinter the political and social fabric of a nation, lead to governmental crises and deadlock, and stymie the compromises so often necessary to preserve freedom and achieve progress. A broad based two party structure produces a degree of political stability and viability not otherwise attainable.”
