Rudy To Endorse McCain?

Mark Halperin and NBC report that Rudy Giuliani expected to endorse John McCain, as early as Wednesday:

A senior Giuliani official told NBC that he will endorse McCain on Wednesday in California, where Republicans are set to debate at the Reagan Presidential Library in Simi Valley.

Asked directly if he was dropping out of the race, Giuliani said only: “I’m going to California.”

Rudy's concession speech sounded like he was ready to pack it in. I expected Rudy to withdraw, but I didn't expect he would endorse McCain.
