It will be interesting to see how Paul reacts to the law—as he'll be forced to do, probably no later than April 7—in light of his libertarian credentials. If he stuck true to them, not only would he support the law but also support the right of Indiana’s businesses to discriminate against LGBT people, something that the rest of the Republican field opposes. (They just disagree with liberals about whether Indiana’s law would allow discrimination.)

But if recent history is any guide, don’t expect Paul to stick true to his libertarian roots. Almost whenever he has faced a choice between traditional libertarian positions and mainstream Republican positions, he has chosen the latter in hope of winning the GOP nomination. Just recently, for instance, he called for more defense spending after saying for years that the military was bloated and needed further cuts.

In fact, Paul has already reversed himself on whether private businesses should be allowed to exclude people from their establishments for any reason. “I think it’s a bad business decision to exclude anybody from your restaurant,” he told the Louisville Courier-Journal in 2010. “But, at the same time, I do believe in private ownership.” He continued, “In a free society, we will tolerate boorish people, who have abhorrent behavior, but if we're civilized people, we publicly criticize that, and don't belong to those groups, or don't associate with those people.” Just a few years later, as that position became controversial, Paul (dishonestly) said that he never held the libertarian position to begin with.

So while it is taking a while for Paul to give his position, it isn’t hard to deduce where he’ll eventually fall. Maybe he’s just waiting until the spotlight on Indiana dies down a bit, so that his libertarian supporters are less aware when he adopts the party line. But if that's his plan, it's not very presidential.
