I think I'd raise here because I have the button and raising seems like an extremely easy way to get to the river rather cheaply with a weak draw, or to find good spots to win unimproved, or to win a decent sized pot if I hit something.

Basically I'm on the button and I want to have the initiative for this hand. Make the limpers a little looser postflop than described in the OP and I change my answer to a limp.
