What effect does the "equal time" law have on Law and Order now that Thompson is a declared candidate?

Answer 1

Law and Order reruns with Thompson in it will not be aired. Thompson has hinted that his "late" (even though it's technically on time and everyone else were way early) announcement was tied into royalties that his costars were getting from the reruns being aired.

Answer 2

Every episode with Thompson in it entitles all of the other candidates to pretend to be someone else on television for an equal amount of time.

There's no certainty that the equal time rule even applies to a television series. L/O doesn't equate to a campaign ad or an interview. It's just that no one wants to risk having the question answered by a judge.
