Rule 40 is an anti-brokered convention rule. It means (in practice) that only the #1 or #2 candidate out of the primaries and caucuses can be the nominee. This year, it's basically the anti-Mitt Romney / Paul Ryan rule, because it keeps them from being nominated by a few unpledged delegates on the first ballot and then winning on the second ballot when the pledged delegates are free to vote how they want.

what if they revoke or change rule 40 when they adopt the new convention rules?
