The Rules and Bylaws Committee of the Democratic National Committee may have made history yesterday, deciding to restore half the delegate votes to Florida and Michigan in the national convention.

New Mexico Governor Bill Richardson, who quit the presidential race Jan. 10, says Barack Obama calls him every three days or so and that about 10 supporters of Hillary Clinton call him every day.

Their goal: obtain his endorsement for president.

The New York Times calls Richardson one of the biggest prospective endorsers in the Democratic Party because he is a former candidate, Hispanic governor and a superdelegate.

Richardson tells the newspaper that he is “genuinely torn.” He says he may make an endorsement next week, or not at all.

Thanks to Woodward, Bernstein and Deep Throat, the first rule of investigative journalism is “Follow The Money.”

The rule works for Muckety, too, especially when it comes to politics. Connections between politicians and their donors are always revealing.

A case in point: A story by Michael Cooper and Leslie Wayne in Thursday’s New York Times. It focused on the wealthy Paul E. Singer, a hedge-fund founder and backer of Rudy Giuliani’s presidential bid.
