Obama Clinches Nomination
Barack Obama has passed the magic threshold of delegates required to win the Democratic nomination, the AP reports.
Barack Obama effectively clinched the Democratic presidential nomination Tuesday, based on an Associated Press tally of convention delegates, becoming the first black candidate ever to lead his party into a fall campaign for the White House.
The AP tally was based on public commitments from delegates as well as more than a dozen private commitments. It also included a minimum number of delegates Obama was guaranteed even if he lost the final two primaries in South Dakota and Montana later in the day.
This is a rather inexact science, since Democratic delegates, especially the unpledged superdelegates, can pretty much vote for whomever they please.
