As Sen. Hillary Rodham Clinton made a last-minute trip to West Virginia and declared her intent to stay in the race, aides to Sen. Barack Obama signaled Wednesday that he would move towards a general election strategy over the next month.

Obama has accumulated a lead in pledged delegates that is all but insurmountable – a point that Clinton campaign officials acknowledged Wednesday in a conference call with reporters. That pushes the campaign largely into political backrooms, as both candidates made plans to meet privately Wednesday and Thursday with uncommitted superdelegates in Washington.

Aides to Obama, who spent Wednesday in Chicago with his family, said the Illinois senator would campaign in the remaining primary states and Puerto Rico. He heads to Oregon, which votes May 20, on Friday for a two-day trip and travels Monday to West Virginia, which votes May 13.  When asked whether Obama would campaign over the next month in general election states, Axelrod said: “I guess you can infer that from what I said.”
