Trump is currently sitting at 950 delegates after tonight's landslide.

In addition, Trump has won anywhere from 66-100% of PA's unbound delegates thanks to Paul Manafort's groundgame, putting his total delegate count at around 1000 after tonight.
Trump needs 1237 delegates to win on a first ballot at the convention, so he needs somewhere around 237 more than he has presently.
Trump is polling ahead in California. We can expect him to take that winner take all state, giving him around 170 delegates.
Trump is also polling ahead in Indiana, where he can win another 57 delegates. That gives him about 230 delegates.
But in addition to those states, there's 8 others that need to vote, with a total delegate count of about 280. Let's say that Trump win's 50% of these delegates conservatively, which is below the actual percentage of delegates he's been pulling from states. So 140. That would give him 370 delegates, or over 100 more than needed to win the convention.
In short, it is now a mathematical certainty that Trump will win the convention on the first ballot, unless something happens to undermine his campaign. Even if he loses Indiana to Kasich, he will win the convention with those other 8 states.
Ladies and gents, Trump won the nomination tonight. Get ready for Clinton v Trump, 2016. Stock up on beer now, because this is going to the YUUUUGE.

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
