More of a guideline, really

The Republican National Committee's "Rule 40(b)"makes eligibility for the GOP nomination contingent upon winning a majority of the convention delegates in at least eight states or territories, an achievement generally accomplished by winning at least eight primary or caucus elections...

Party officials and knowledgeable sources have confirmed over the past few days that Rule 40(b) doesn't exist for the purposes of the upcoming convention. That means at this point, the three candidates left in the race...are all eligible for the nomination, as, possibly, are...contenders who have since suspended their campaigns.
