For four days ending Sunday, a quartet of presidential hopefuls trooped to Las Vegas to attend the annual gathering of the Republican Jewish Coalition.

Impresario: Sheldon Adelson, the Vegas-Macau casino mogul whose fortune is estimated at $39 billion – 8th richest man on the planet – and who dumped $92 million into the election of 2012.

Adelson kept Newt Gingrich alive with a $15 million infusion of ad money, gutting Romney, and then sank $30 million into Mitt’s campaign.

This time Sheldon wants to buy himself a winner.

Ari Fleischer, press secretary to Bush 43, and a member of Adelson’s RJC fiefdom, put it plain and simple: “The ‘Sheldon Primary’ is an important primary. … anybody running for the Republican nomination would want to have Sheldon at his side.”
