Trump victory in Indiana, surprise to other republican

Cruz's exit came as a surprise, and many Republicans who had denounced Trump were grappling with what to do next.
Reuters/Ipsos polling in April found Cruz supporters split on whom to support if their candidate quit.
Lanhee Chen, who had advised former Republican candidate Marco Rubio, on Tuesday night floated the possibility of a third-party candidate.
"Tonight's outcome raises seriousness & urgency of discussions about third-party alternative; how real it is depends on who steps up to run," he tweeted.
Other prominent Republicans said they would support Trump. "It's binary now. It's Trump or Clinton, my vote's for Trump," former Louisiana Governor Bobby Jindal, who dropped his own White House bid in November, said on Fox News.
