Campaign Countdown: Sanders hanging on

SAVANNAH, GA (WTOC) -

Republicans are already looking forward to the fall while the primary battle rages on for the Democrats.

Bernie Sanders continues to get his share of primary wins, but hasn't been able make much of a dent in the overall delegate count against Hillary Clinton.

Sanders vowing again this week to fight on all the way to the convention. Clinton is close to clinching the democratic nomination - about 90 delegates away - thanks in part to an overwhelming majority of so called super delegates who have pledged to support her. 

Some are party leaders you probably have never heard of. Others are elected representatives such as John Lewis in Georgia or Jim Clyburn in South Carolina—both have pledged for Clinton. 

There's also former President Jimmy Carter, who hasn't committed yet as well as former President Bill Clinton who has, for Hillary.

"They are allowed to be superdelegates just by seniority and accomplishments and then they are free to vote for anyone they want.  And this accounts for a lot of Hillary's lead,” said SSU Political Scientist Dr. Bruce Mallard.

Indeed it does, Clinton has around 524 pledged superdelegates compared to just 40 for Sanders.

"There are many superdelegates now quite incredibly who are supporting Secretary Clinton in states that we have won 60 to 70 percent of the vote. We think we have the right to make the case to those superdelegates go with the majority of your state,” said Sanders.

"He hopes to go to the convention and convince them that he is a better choice—more electable than Donald Trump, but I don't think they will change,” said Dr. Mallard.

Sanders is also pushing back against accusations that his supporters nearly came to blows with Clinton backers last weekend in Nevada—that has democratic party leaders calling for unity.

"Everybody needs to take a step back and a deep breath.  We have to make sure that we can do everything we can to maximize the likelihood of being unified,” said DNC Chairwoman Debbie Wasserman-Schultz.

There is growing concern in the Democratic Party that this ongoing battle could end up helping Republicans in the fall. A new national poll - that I should point out came from Fox News - shows Trump over Clinton in a November election by three points. 

Back in April, that same poll showed Clinton with a seven point lead over Trump.
