Gallup has always found political independents to be most desirous of a third party, and 68% currently are. But right now there is also a significant party gap, with 52% of Republicans favoring a third party, compared with 33% of Democrats. This is the first time Gallup finds a significantly higher percentage of Republicans than Democrats in favor of a third party. During much of President Bush's term, the opposite was true, with Democrats more likely to favor the formation of a third party. That gap narrowed in 2007, after the Democrats' victories in the 2006 midterms, and there has been a minimal difference between the two parties until the current poll.
