“I’m a purist — the rules shouldn’t be bent for him or anyone else,” said Leslie Tassin Sr., an unbound delegate from Louisiana.

Tassin was previously bound to Rubio, but now that the Florida senator has dropped out of the race, he’ll likely head to the convention able to side with the candidate of his choice.

He’s among a handful of unbound delegates who are known at this point in the process. Most will be selected at state conventions over summer.

State bylaws require House, the unbound delegate in Colorado, to stay neutral in the race until he casts a ballot at the convention in July. Still, he offered some clues as to the factors that will shape his decision.

Like Tassin, House said that if one of the candidates arrives with a strong plurality of delegates, that he wouldn’t feel obligated to push that candidate across the finish line solely by virtue of them coming the closest.
