Assuming my reading is correct, according to Rule 40(b) of the Republican National Committee Rules governing the convention, only candidates who have received the majority of delegates from 8 or more states can be considered for the Presidential Nomination. So that would likely rule Kasich out as a potential nominee. And the rule would narrow the field down to either Trump or Cruz:

Each candidate for nomination for President of the United States and Vice President of the United States shall demonstrate the support of a majority of the delegates from each of eight (8) or more states, severally, prior to the presentation of the name of that candidate for nomination. Notwithstanding any other provisions of these rules or any rule of the House of Representatives, to demonstrate the support required of this paragraph a certificate evidencing the affirmative written support of the required number of permanently seated delegates from each of the eight (8) or more states shall have been submitted to the secretary of the convention not later than one (1) hour prior to the placing of the names of candidates for nomination pursuant to this rule and the established order of business.

Not true.
They have the authority to rewrite the rules up to the day before the convention.
This is the test to win and then they will move the goalposts.

Problem is, they risk losing the House and the Senate if they do it, and they risk losing the House and Senate totally two years later if they do it along with Governors, state legislature, judges, etc.

The problem is the GOPe can change that rule prior to the convention.

The rules committee meets again before the convention and will change the rules to whatever serves their establishment purposes. Count on it.

Rule 40 can be waived
