Here's a short story:

San Francisco, California (CNN) -- President Obama will wake up in San Francisco, California, on Friday amid a five-state, four-day tour aimed at propping up embattled key Senate incumbents. 

Obama will fly to Los Angeles, California, to attend a fundraiser luncheon at the University of Southern California for Sen. Barbara Boxer and former Gov. Jerry Brown, before delivering remarks at a Democratic National Committee rally at USC's Alumni Park. 

Boxer has opened a slight lead against Republican Carly Fiorina, as has Brown in his effort to win his old job back in a nasty battle with Republican Meg Whitman. National Democrats are still watching these races closely to ensure they don't slip out of their hands. 

By Friday evening, the president will be in Las Vegas, Nevada, to attend a DNC rally at a middle school before heading to a private residence for a fundraising event for Sen. Harry Reid and the Democratic Senatorial Campaign Committee. 

Reid is stuck in the mid-40s in most polls, despite months painting his Republican opponent, Tea Party-friendly Sharron Angle, as an extremist. 

On Saturday, Obama heads to Minnesota for a rally to support former Sen. Mark Dayton, who is running for governor. The president also will headline a fundraiser for the Democratic Congressional Campaign Committee before heading back to the White House on Saturday evening. 

In addition, the president will attend another congressional campaign panel fundraiser Monday in Rhode Island before taking four days off from campaigning to tend to other business at the White House.  (End of story)
