A writer for FiveThirtyEight calculated what the Democrats' pledged delegate count would look like if their primaries followed Republican delegate rules.
He found, under those rules, Clinton would jump from a 289-delegate lead to a whopping 977 lead.

The current U.S. Secretary of Labor is considered a sleeper pick by many Democrats because he is not well known outside of D.C., but some believe his strength and popularity among union workers and other progressive groups could be an asset to Clinton's ticket.

The Independent from Vermont has become Hillary Clinton's primary rival for the Democratic nomination, garnering a surprising amount of support. Bringing Sanders onto the ticket could help to unite both sets of supporters who have been split in Democratic primaries.

The Secretary of Agriculture since 2009, Tom Vilsack also served as the governor of Iowa from 1999 to 2007. Vilsack could bring some governing experience along with swing state influence.

Evan Bayh could bring a more right leaning brand of politics to the ticket. Bayh previously served as the junior U.S. Senator from Indiana from 1999 to 2011, and also as the 46th Governor of Indiana from 1989 to 1997.
While the likelihood of him agreeing to take on the veep job again might be low, Biden's popularity among Democrats would likely boost Clinton's chances.

Hillary's husband is technically allowed to serve in the job, and some legal experts even think he'd be able to take office if necessary. Unfortunately for the diehard Clinton supporters, a Clinton-Clinton ticket will probably be a dream that never comes true.

How is that possible? Well, when it comes to assigning delegates to candidates, Democrats use a proportional system.
However, on the GOP side, rules like viability thresholds, winner-take-most districts and statewide bonuses allow a Republican candidate to snag the majority of a state's delegates, even if that state has decided to use a more proportional allocation method.
The FiveThirtyEight report notes this was meant to help end the race faster: "This was, in part, designed to give a candidate who is doing well early on a boost in delegate momentum."
Ironically, the nationwide debate over whether the primary process on both sides is "rigged" has actually focused on disadvantages to Bernie Sanders and Donald Trump.
Namely, both candidates decry that delegates hold so much power and that it's not a popular vote that decides the nominee.
