Recent delegate counts show that Ron Paul is picking up a part of the anti-Romney protest vote, and he remains popular among young voters, but it's unclear if that will amount to anything.

There are a number of compelling reasons why Ron Paul might want to drop his presidential campaign.
First off, Mitt Romney has pretty much won the GOP nomination. That means the single-digit chance Congressman Paul had of sitting in the White House has now fallen to a number perilously close to zero.
Second, the trail is long, and the days are hard. Food is bad and sleep is limited. It can be tough to find the time to get in a good walk in the morning and an afternoon bike ride, as Paul likes to do.
But Paul remains in it, if not to win it, then to promote his ideas. He’s long said that he wants to build a political movement as much as anything else, and if you look at his upcoming events, they remain heavy on appearances at colleges, which remain his most fertile ground for winning converts.
