Jonah Goldberg analyzes for National Review Online one key factor in today’s political battles.

Here’s a theory for why our politics are so confusing these days: Neither party wants to be a majority party.

From an ideological perspective, majority parties are, by nature, weird. For instance, the long-dominant FDR coalition included a strange mix of blacks and segregationists, corrupt city machines and the reformers who hated them.

Over the several decades that followed, most major policy questions were hashed out within the Democratic party. The Republicans factored in mostly as stalemate-breakers. …

… Samuel Lubell, a Polish-born political analyst, famously described this dynamic as the “sun and moon” system of political parties. In our “political solar system,” Lubell wrote in 1951, “it is within the majority party that the issues of any particular period are fought out; while the minority party shines in reflected radiance of the heat thus generated.” …
