When will Santorum finally throw in the towel?

[True Federalist (진정한 연방 주의자)]

Quite possibly not until after his last chance to gain pledged delegates, the Nebraska State Republican Convention which is tentatively scheduled for Bastille Day.  Even if it doesn't affect his chance at being nominated, it may make a difference on the platform.

In any case, Santorum will not throw in his towel before Gingrich and Paul have.  Santorum needs to make certain he is in charge of the #2 spot on the delegate count so as to be able to take advantage of the mess that would result if Romney should have to pull out unexpectedly for reasons unforeseeable.
