It might seem counterintuitive, but the chances of Bernie Sanders winning the Democratic nomination actually got worse after the Vermont senator won the Indiana primary on Tuesday night.

Sanders won 52.5% of the Hoosier state’s vote, compared with 47.5% for former Secretary of State Hillary Clinton, according to the Associated Press.

But Indiana awards delegates on the Democratic side proportionately. The AP says 43 delegates have gone for Sanders, compared with 37 for Clinton. There are another three to be allocated depending on final vote tallies.

So the latest national tally for delegates has Clinton on 2,202 — consisting of 1,682 pledged delegates and 520 so-called superdelegates, luminaries like former President Bill Clinton and Barack Obama.

Sanders has 1,400 delegates, with 1,361 pledged delegates and 39 superdelegates.

Bernie Sanders: Campaign isn't over yet

There are 2,383 delegates needed to secure the nomination. So the odds of Sanders winning the nomination actually got longer after the Indiana win, because there are just a few states left for the 74-year-old to win delegates. (California and New Jersey are the largest prizes still remaining.)

Even assuming he captures the three as-yet unallocated Indiana delegates, Sanders will need to win 88% of the remaining delegates at stake. Before Indiana, his challenge was to win 82% of remaining delegates.

Now, the Sanders camp has said it would fight to switch over the superdelegates to his side, arguing that he’s the better candidate to fight Donald Trump in a presidential election.

But it’s hard to see how that effort will be successful, given that he’ll trying to persuade the superdelegates not to back the candidate with more votes, as well as the fact that the superdelegates are the very definition of the establishment that he’s spent the whole campaign fighting.
