With Marco Rubio out of the race following a crushing defeat in his home state, attention has turned to the 163 delegates the senator amassed before Tuesday, which could be the key to the nomination in the event of a contested GOP convention. But Rubio won't be able to simply hand the delegates to another candidate, the Huffington Post explains. The rules for delegate allocation vary greatly from state to state, and of the 19 states where Rubio has won delegates, more than half—accounting for 134 of his delegates—require delegates to vote for him in the first convention ballot whether he's in the race or not. Only nine Rubio delegates are from states that release delegates to choose again as soon as their candidate drops out.
Rubio didn't endorse another candidate when he spoke to supporters in Miami on Tuesday night, though he made some comments clearly aimed at Donald Trump, Politico reports. "America needs a conservative movement, one that is based on ideas, principles," he said. "Not on fear. Not on anger. Not on preying on people's frustrations." Rubio—who finished nearly 20 points behind Trump in Florida—spent years building a base among establishment Republicans and mastering policy issues, only to be undone by a race in which anger was more important than policy and GOP voters abandoned the establishment, the Washington Post finds in a post-mortem on his candidacy.
