Yes. Copyright is essentially a settled political issue; both sides, as a matter of platform, seem to believe it should last as long as possible and reserve as many benefits as possible to its creators. Of course, this is not what the public believes, but since copyright legislation is usually labeled something emotionally manipulative and dishonest like "The Mickey Mouse Protection Act" and since the media has an interest in presenting that legislation in the most favorable light possible, no one ends up opposing the specific bills.

As such, all current candidates, with the possible exception of Sanders, would probably consider signing a copyright bill routine (Lessig isn't a candidate anymore).
