If you want to see which candidate is beholden to the unions, look at the mailers you receive.
Look for the union "bug", the union made logo. All of Kobayashi's pieces has the bug on it.
None of Choy's does.
Look at the mailer you just received from Caldwell, there's a bug on it.
Then look at Djou's, no bug
Tell me who you think has your interest in mind.
