If Fred Thompson decides to run for President, it's a no-brainer that he'll leave his current role on Law & Order, but The Washington Post reports that Law & Order might have to leave him too — and stop rerurns of Thompson's episodes of the show in order to honor the equal-time provision. Here's how it works: The equal-time rule requires that if a TV channel gives out screen time to one candidate, they have to also offer free time to other candidates. (News interviews don't count.) So if Thompson runs for President, his screen time on Law & Order could potentially be counted as a requirement to give out free time to the other Republicans, from Rudy Giuliani to Tom Tancredo. And since TV networks are loathe to even risk that kind of litigation, expect his episodes to go off the air if he jumps into the race.
