Cutting back perennials in fall

Should I cut back my veronicas in the fall?
Doug says that cutting back and cleaning up all perennial plants is a good idea. You want to leave the garden in the fall as you want to find it in the spring.
But having said that, there are times when you can't get to those chores (funny how life gets in the way sometimes). The plants will be fine even if you don't cut them back. They'll be all rotted and flopped down on the ground in the spring (you can clean them up then or mulch over top of them) but the plant should be fine either way.
