Pivotal politics

Politicians and pundits alike have complained that the divided governments of the last decades have led to legislative gridlock. Not so, argues Keith Krehbiel, who advances the provocative theory that divided government actually has little effect on legislative productivity. Gridlock is in fact the order of the day, occurring even when the same party controls the legislative and executive branches. Meticulously researched and anchored to real politics, Krehbiel argues that the pivotal vote on a piece of legislation is not the one that gives a bill a simple majority, but the vote that allows it.
