I would say just let them be. Basically what the deer have done is pinch the tops out of your plants and although you have lost the initial blooms the plants will respond by becoming bushier and will produce more flowers. In a short period of time you should see new stems growing at the leaf axils ( where the leaves meet the stem) and each one will produce blooms provided Bambi finds another place to dine. The exuded sap will dry and the plant will heal itself so I wouldn't be concerned about either.
Cyclops is right - the deer pruned them for you since they knew you couldn't stand to do it. Do you have a dog? Mine are the guardians of my back yard.
If you don't get some deer repellent happening, you won't have to worry about the leaking sap for very long, since the deer won't mind eating your plants to the ground! I use rotating combinations of Irish Spring Soap, garlic clips and Liquid Fence.
