The threat of violence among Donald Trump supporters has a lot of people scared, but that fear could actually become a central part of his stategy going into any contested Republican convention.

Once the dust settles on primaries being held tonight in Florida, Ohio, Illinois, Missouri, and North Carolina, we’ll have a better sense of whether Trump is likely to secure the 1,237 delegates needed to win the GOP nomination outright, or if he’s more likely to come up short, leaving it to delegates to decide the nominee on the convention floor.

This will put Republicans in a difficult position. On the one hand, many of them want to stop Trump from winning the nomination at all costs, given that he isn’t ideologically conservative and would do grave damage to the GOP brand and to candidates running for House and Senate. But on the other hand, there’s the fear of a backlash among Trump supporters if he comes into the convention with the most delegates and after having won the most states, but is denied the nomination by political elites.

And that’s where the threat of violence comes in.
