AP is reporting that the Romney and Paul campaigns are worried about the possibility of voter fraud because there will be a post-Shabbat (after sundown) special caucus meeting in Clark County, Nevada to accommodate religious Jews who cannot participate in an earlier caucus this day.

It appears the concern is that some voters will go to both a day caucus and the evening caucus—though AP says that fewer than 300 people are expected at that later caucus.  Concern about voter fraud in this instance seems quite exaggerated.  Really?  A flood of fake Orthodox Jews to cast additional votes?
