The graph of how many delegates each candidate currently has shows both candidates with more than half of the delegates needed to win. It’s a race to the dashed line at the top, with Clinton still comfortably ahead.

Below, we see what percentage of delegates awarded to date have been won by each candidate. The goal here is to stay above the dashed line. In our two-person Democratic contest, the lines for both candidates move in lovely symmetry.

As time wears on, it becomes harder and harder for Sanders to make up lost ground. Below, we can see the percentage of remaining delegates each candidate would need to win to secure a majority of pledged delegates. The massive Sanders wins of last weekend look much less dramatic on this graph compared to the first one, mostly because of the scale.

The Republicans

The GOP side shows little change since the last update. Donald Trump continues to expand his delegate lead over Ted Cruz:

Cruz and Kasich lag far behind. Kasich can no longer get up to the dotted line, while for Cruz, it’s a near impossibility.

Indeed, it’s mathematically impossible for Kasich to win a majority of delegates. Trump only needs a little more than 50 percent, which is entirely possible.

Trump currently has just under 50 percent of the total delegates awarded to date, but Cruz is stuck at around 30 percent.

We’ll check back in after the start of Act II!
