Our best guesses as of :

We’re estimating the number of delegates each candidate will pick up in tonight's primary using Indiana’s delegate allocation rules, our expectations of each candidate’s performance, the voting results in other states, and the demographic makeup and historical patterns of Indiana voters. As votes come in, we expect the uncertainty around our estimates to narrow.

We are running several different models for each candidate in each state; each line in the charts above represents a different model.

We’re also making live estimates for Democrats. Follow detailed results for both parties here.
