Under the old rules, the "dishonest" thing to do is register for the party who's beliefs you least agree with, and then in the primary, vote for the candidate less likely to win in the general, in order for your actual preferred candidate to have a better chance at winning.
That is to say, game the system by looking at the rules and vote for someone you don't actually believe in. (In the primary.) Whether or not that rises to the level of being dishonest is up to you to decide.
(The "new" rules are that the "less likely to win" candidate may be harder to determine in the current political climate.)
