It's Over, He's The Nominee

The conventional wisdom is shifting, finally, after Obama's resounding victory in North Carolina and narrow loss in Indiana last night.

George McGovern - who is not currently a superdelegate, but will likely be the add-on elected at South Dakota's June convention - endorsed Obama today, saying it's time for the party to unite. Another superdelegate switched from Clinton to Obama today, and Obama's campaign says the magic number to clinch the nomination is 170.

The math is virtually impenetrable for the Clinton campaign at this point, and in 13 days Barack Obama will clinch a majority of pledged delegates. By Memorial Day, Obama will win a majority of the delegates required to clinch the nomination. By the last primary on June 3, Clinton will drop out and endorse Obama.
