It’s not over till it’s over
For someone who has the nomination supposedly locked up, Hillary Clinton is sure losing a lot of primaries (seven of the last eight counting Democrats Overseas). According to FiveThirtyEight Sanders needs to win about 58% of the remaining vote to catch Clinton in pledged delegates, which sounds extremely unlikely, but . . .
As for the Republicans, Trump losing by 17 points might well mean something, although it’s just one state, and a state where right-wing talk radio went all out against him. FWIW the Iowa electronic markets now have it as 44% Trump, 27% Cruz, and 28% the field. Stock up on the popcorn.
