Ballotcraft: Trump and Clinton

This fantasy politics game, founded by two Stanford grads, has thousands of players who use fake money to buy “shares” in candidates. So far, it has correctly predicted 60 of the 72 nominating contests it has covered as of one day prior to voting.

As of Sunday, shares of Trump were worth at least $0.75, meaning his chances of winning exceed 75 percent, in Maryland, Connecticut, and Delaware. In Pennsylvania and Rhode Island, the site’s users put Trump’s chances of winning at a minimum of 65 percent.

Clinton had the advantage in Maryland, with a 76-percent chance of winning; in Delaware, with 65-percent odds; and in Pennsylvania, with 59 percent. In Connecticut, where the two Democratic contenders exchanged the lead a few times earlier in the month, Clinton shares are worth around $0.59, up from a low of $0.49. The only real bright spot for Sanders is Rhode Island, where he has led since April 9 and currently has a 62-percent chance of winning.
