Watching MSNBC Tuesday night, we caught NBC political director Chuck Todd, whose political insights are widely respected, delivering a solemn pronouncement about the state of Hillary Clinton's campaign. According to Todd, by the end of Tuesday's contests, Barack Obama will likely have a lead of 150 pledged delegates and an overall lead (counting superdelegates) of 80 delegates.

This lead will be very difficult for Clinton to overcome, Todd told viewers. "All the contests that are remaining ... if Hillary Clinton was to win all of them, she would need to win 58 percent of the pledged delegates, at this point, just to get the lead again in pledged delegates," Todd said. When likely Obama victories are factored in, that share rises to 65 percent.
