There were two sets of rumors circulating before and after the vote yesterday. As with every election and party primary, there were allegations about vote-buying and electoral irregularities in the Arab sectors, where particular communities or towns often vote en bloc for one candidate (see for example this story on Ghajar). Perhaps more importantly, the state comptroller is apparently investigating fiscal improprieties in the Mofaz campaign (Ha'aretz Hebrew). Apparently, the Mofaz campaign accepted donations in excess of the allowed sum per donor, which is set at 40,000 NIS. According to Ha'aretz, Mofaz received the following donations from four American businessmen:
$99,970 from Allan Meder (?)
$100,000 from Lucian Salls (sp?)
$50,000 from Yakov Menahem
$18,000 from David Amrani
I couldn't find anything on these individuals - I'm sure that more will emerge shortly.
