Poli Sci Prof Shugart analyzes the unintended effects of "presidentialism"
Matthew Shugart, a political scientist at UC San Diego with whom I've become acquainted, has a new book he co-authored regarding the way the very concept of a president affects party politics and tends to "personalize" politics. At least that is what I am gleaning from a quick skim of the volume. Assuming I have accurately summarized this, the book is analyzing the institutional behavoir and challenges presented in our non-parliamentary system, among other systems, in a fascinating way.
I have long believed a multi-party parliamentary system would have a salutary effect on our political discourse by providing a platform for a Labor and Libertarian sort of politics (Although I'm definitely settling for instant run offs as an initial compromise!). In the US, as Gore Vidal (among others) have noted, we have only one party: The Property Party, with the two wings called Democratic and Republican. That the Republicans have become the Crazy Party does not appear to have undermined the Propertied Class' interests to any significant extent.
