What are they thinking?

This is the primary. 1% of the voters in New Mexico so far voted uncommitted.

In a way, I can see some wanting to keep their options open, but why go to the trouble of voting at all?

1. Just a wiild guess-- Could these have been supporters

of one of the candidates who dropped out.-- and really really
were unwilling to accept the ones left in the race.

There are people who simply vote the parts of the ticket
they really believe and support.

For example if you do not like the Presidentia; Candidate
often you just leave it blank and complete the rest of the
ballot.

Uncommitted in that number does seem weird.
