It’s not “stupid”; it’s “malignant narcissism”. With Cruz’ personality disorder he absolutely sees nothing unethical or wrong with what he’s done. Bottom line: With those people the world is there for their benefit and to further their successes, so nothing is out of bounds.
Do you understand the mechanism behind party primaries? It never was strictly a "most votes wins" proposition.
Do a little (or a lot of) research before you sling the word "dumb" around.
