The reason I am confident that Trump would crush Kasich is because this election is an anti-Establishment election.

Some states have been anti-establishment, but others were pro-establishment. I do not want to give the pro-establishment forces a chance to unite. If the last few primaries are a two-man race presented as an up or down referendum on Trump, even people who don't like Kasich might vote for him to try for a "compromise" candidate at the convention. Party leadership would even argue that they were justified in treating that as a public rejection of the Trump nomination. The rules changes to deny Trump the nomination would be "to meet the public demand". No, thank you.

That is what can happen now, as long as Kasich is still running, which is why the Establishment want him to keep running.

Both Cruz and Kasich need to drop out.
