Will Rottenborough Delegates Save Trump?

How should a party handle delegates from states that are not likely to vote for the party in the fall?  Delegates that Theodore Roosevelt termed Rottenborough Delegates.  Criticism of them in the Trump-Cruz contest and the Sanders-Clinton contest is not new.  A debate in the 1860 Republican Convention once again is relevant today, as Trump chances to obtain a fight-free convention depend entirely on delegates from states the party will not likely contest seriously in the fall.   We asked this question in 2012 when this podcast was first recorded, with Romney, and we ask it again. Also a plug to the upcoming(summer 2016) Extra Podcast from My History Can Beat Up Your Politics.
