Obama Campaign Manager, David Plouffe estimates his candidate has a 136 pledged delegate lead after yesterday’s Potomac Primary wins. The Obama campaign has now won 21 contests (including 12 primaries) and, according to the campaign, has a 700,000 vote lead in terms of popular votes cast. “We couldn’t be in a stronger position right now, and the last really five days, we believe, will be looked at back at as a very decisive period in the nomination contest,” he declared. “We think it really put us on the path to the nomination.”

On a conference call with reporters, Plouffe said his candidate has the advantage. “We believe it’s next to impossible for Senator Clinton to close that pledged delegate count. The only way she could do it is winning most of the rest of the contests by 25 - 30 points. And we see not a single contest on the calendar left where we’d expect her to win by those kind of margins.” He later explained that they expect to benefit from a more relaxed primary schedule because “we believe anytime Senator Obama is able to spend time with voters in states, we have profited from that.”

The only way Senator Clinton could overcome this gap, Plouffe said, is if she wins both Texas and Ohio by “blowout” proportions - meaning a 20 point margin or greater as to win a large proportion of the delegates at stake. But Team Obama doesn’t expect that to happen - in fact, they plan on amassing more delegates themselves in both states. “At this point, even the most creative math, really does not get her ever back even in terms of pledged delegates,” Plouffe said, saying it would be “highly unlikely” that their pledged delegate lead will be eroded.

So does this mean victory or will superdelegates decide the Party’s nominee? “We believed all along that the pledged delegate leader will be the Democratic nominee of the party,” Plouffe stated. “I think there’s a growing chorus of concern out there that people do not think that superdelegates should overturn the result of the contests, so we have closed the gap with superdelegates, we’re continuing to try and attract support and we’ll continue to do that. But I think at the end of the day, if we head into June and we’ve won more states, more importantly we have a pledged delegate lead, you know at the end of the day, I think it’s much more likely than not that the superdelegates ratify that outcome,” Plouffe said.
