Numerous accounts reveal that congressional leaders often secure “hip‐pocket votes” or “if you need me” pledges from rank‐and‐file legislators. These are essentially options on votes. Leaders exercise sufficient options—pay legislators to convert to favorable votes—when those options will yield victory. Otherwise, they release the options. A model shows that this optimal strategy for leaders produces many small victories, few small losses, and losses that are, on average, larger than victories. We find precisely these patterns, hence strong evidence for vote options, in Congressional Quarterly key votes from 1975 through 2001 and in non‐key votes from the 106th Congress (1999–2000).  相似文献

CROOK  RICHARD C 《African affairs》1997,96(383):215-242
Why is that former dominant or single party regimes, especiallythose in Africa, have generally survived and even emerged strengthenedafter the introduction of multi-party competitive elections?In Côte d'lvoire since 1990 the ruling party has beenable to win elections by using incumbency to present itselfas the organization most likely to be capable of putting togethera winning coalition. In a society segmented by a multiplicityof cultural and religious divisions and where political poweris a zero-sum game, the logic of democratic representation meansthat no group can afford to be excluded. Yet in the 1990 and1995 Ivorian elections .the opposition attacked die ethnic characterof the government and deliberately mobilized ethnic minorities,regional and religious (Islamic) sentiments. They thereforefailed to escape, in electoral terms, from their extremely localizedstrongholds. Their attempt to mobilize around an anti-foreignerplatform in 1990 rebounded in 1995 when the government itselftook over their ‘ultra-nationalist’ stance by excludingnon-Ivorians from the elections. The consequent exclusion ofthe opposition's favoured Presidential candidate and the failureof the opposition alliance to agree on a non-northern, non-Islamicalternative candidate led to a violent boycott and the eventualcollapse of the opposition alliance.  相似文献

THE Great Dragon has been courting foreign business and cultural aspects for more than two decades now, and what is perhaps the West's biggest commercial festi- val is becoming more popular here in China with every passing year. There's a new plump and jolly man in town that loves the color red, but he wears a long white beard and drives a sleigh. The newcomer carries with him a traditionthat the other may or may not admire: in December his picture is posted up on countless walls, but in fla…  相似文献
