Nate Silver: “Clearly tonight’s results were problematic for Trump in terms of his delegate math. A few weeks ago, we’d projected Trump to win 25 delegates in Wisconsin. It looks like he’ll only get 3 to 6 instead. After also accounting for Trump’s failure to get any delegates in Utah last month, our estimate would now project him to get 1,179 to 1,182 delegates total, or somewhere between 55 and 58 short of the 1,237 he’d need to clinch the nomination. Trump could potentially make up the difference by persuading uncommitted delegates to vote for him, although given how poorly Trump’s doing in the delegate-wrangling business, that might not be easy.”
“But the more immediate question — the one I’m not quite ready to answer — is what tonight tells us about how Trump might perform in subsequent states.”
