At the most, Olmert diverted some campaign donations for personal use. That is the common practice among politicians, and the line between campaign and personal expenses is often blurred.
But the critical criterion of bribe is the misuse of official position in return for payment. Olmert is not reported to have made any favors to Talansky at Israel’s expense.
It is ludicrous to speak of Olmert’s embezzlement of campaign donations after, say, Barak and Lieberman gave the Gaza offshore gas field to Arafat to pass it to British Gas in circumvention of Israel’s tender regulations.
