There are still the NE primaries this week and next. According to most polls, Trump is going to do well.
Cruz is the one who needs to be concerned. He is still lagging Trump by about 200 delegates and his only hope remaining is California. If Trump scores high in NY, it may be mathematically impossible for Cruz to get to 1237 delegates.

Not “may be”... IS. (Practically speaking).
Just as it his highly unlikely for Trump to take a majority of delegates into the convention and win on first ballot.
It WILL come down to what happens in subsequent ballots at the convention.
The smart campaign knows this and plans and executes accordingly.
