SOME PRETTY SERIOUS IRONY HERE FROM SISTER SUPERDELEGATE: Team Clinton: Sanders ‘rigging the system’ with quest for superdelegates.

Hillary Clinton’s presidenital campaign on Tuesday accused Bernie Sanders of “rigging the system” by seeking to pick-off the superdelegates that have already pledged their support to Clinton.

“Really, I think when you talk about rigging the system, that’s what Sen. Sanders is trying to do now,” Clinton spokesman Brian Fallon said on CNN’s ‘New Day.” “Hillary Clinton has won in the popular vote by a wide margin. She’s got more than 2 million votes over Sen. Sanders in all of the contests when you add them all up.”

Sanders has been on a hot streak, winning seven of the last eight contests.

But the Democratic Party’s proportional allocation of delegates has made it difficult for him to cut into the big lead in pledged delegates Clinton built up early through landslide victories, particularly in the South.

Clinton currently has about 1,287 pledged delegates against 1,037 for Sanders.

But among superdelegates — party leaders that are not bound to the popular vote in their states — Clinton racked up a massive early lead and counts 469 supporters compared to only 31 for Sanders.

The Sanders campaign is seeking to block Clinton from obtaining the 2,383 delegates needed to win the nomination, forcing a contested convention.

Is it just me, or is Hillary starting to seem nervous?
