| Barack Obama will reach a significant milestone Tuesday as he marches toward the Democratic nomination for president - a majority of pledged delegates at stake in all the primaries and caucuses. |
Obama will still be short of the overall number of delegates needed to clinch the nomination, unless he were to suddenly receive an avalanche of endorsements from the party and elected officials known as superdelegates. But the Illinois senator's campaign is touting the delegate milestone as a big step in defeating his rival, Sen. Hillary Rodham Clinton of New York.
"A clear majority of elected delegates will send an unmistakable message — the people have spoken, and they are ready for change," Obama campaign manager David Plouffe wrote in a memo to supporters Monday.
