The Republican presidential candidates will confront one of the country's more divided electorates in Nevada's Saturday caucus. The state's Ron Paul faction is particularly powerful--it took over the state GOP convention in Reno four years ago and helped get archconservative Sharron Angle to face Harry Reid in his successful re-election bid in 2010. That helped splinter the GOP in the state, with many Republicans now so far apart that getting them to fall behind an eventual presidential nominee is likely to be difficult.
