A member of the RNC rules committee says Donald Trump will likely become the nominee for the GOP if he achieves at least 1,100 pledged delegates ahead of the convention in July even though that is less than the 1,237 delegates needed to secure the nomination.

"If Donald Trump exceeds 1,100 votes, he will become the nominee even though he may not have 1,237," lawyer and RNC member Randy Evans said on MSNBC's Morning Joe [relevant portion of the video begins at 4:44]. "If he gets less than 1,000 delegates then I think we are looking at a contested convention that could go on for many, many days."

Evans said it is highly unlikely that Trump will now win the majority of delegates before the convention but if he secures enough he can win by attracting unbound delegates and those released by other candidates.

Evans explained that there are no provisions in the rules for Jeb Bush or Paul Ryan to be voted in from the convention floor and that only those candidates that have won at least eight states will be called out during the roll call - effectively meaning only Trump or Ted Cruz.
