New York is huge liberal.
Trump got 528,792 votes in the Primary.
Hillary got 1,057,347. That’s twice as many as Trump. It is more than Trump, Cruz and Kasich combined.
Bernie got 766,023.
Kasich got 218,796. Cruz got 126,984.
Republicans got 874,572 total.
Let’s say Trump gets 20% of Sanders’ voters and all Cruz and Kasich’s. Hillary gets Sanders’ other 80%.
Then it is Hillary with 1.67 M votes vs Donald with 1.02M.
Are there 650,000 independents to make up that gap?
Say Donald gets 50% of Sanders’ voters. That would be 1.44 M for Hillary, 1.26 M for Trump.
In the general there will be more voters total and more chance for Trump to gain with that group that did not vote in the primary.
But the numbers show what Trump is up against in New York.
The reason that de Blasiko won the NYC mayoral race, is that only 25% of registered voters voted and that's all you need to know; really!
Now add in the people who for one reason or another didn't vote in the primary, those who couldn't vote in the primary, and those who shall change whom they voted for in the primary and you just might come to a closer to reality figure of what November's vote totals will be in N.Y. state.
There are more then enough Independents to fill in the gap!
The election was only a fraction of actual voters.
