Newt Gingrich is campaigning Monday in California, holding events in South El Monte and Pasadena. The Golden State, which has 172 delegates, doesn’t hold its primary until June, which might make one wonder why Gingrich is spending time there now when the Super Tuesday races loom. (His camp is likely smarting over a National Review editorial out Monday morning urging Gingrich to step aside to make way for a Romney- Rick Santorum contest.)

Santorum, who on Sunday called Romney’s attacks on his record “desperate,” is spending the day out in Tacoma, Wash. He plans an evening rally in the state, which holds its caucuses on March 3 and awards 43 delegates.
