Who does the GOP Draft in the Event of a Brokered Convention?

Almost certainly Cruz, since it would presumably be caused by a 3-way delegate split between Trump, Cruz and Rubio. The first thing the establishment would do is try to get all the superdelegates behind Rubio and use various inducements to try to poach delegates from Trump and Cruz, with the goal of getting Rubio to a majority or close enough to a majority that he's the only possible nominee. But failing that, the Trump and Rubio camps aren't going to make a deal with each other, so Cruz would have all the leverage needed to be the nominee; if one side won't back him he can threaten to do a deal with the other.

If for whatever reason Cruz isn't a plausible nominee (for example, that he's a distant third in the popular vote, that he dropped out, that he burned all his bridges with the Rubio camp or that he had a major scandal), then the party establishment would, once again, try to nominate Rubio. Failing that they'd try Paul Ryan, and if they can't get someone who toes the party establishment line on immigration then, at that point, they'd turn to Romney.
